Abstract

In an in-vehicle equipment control apparatus that includes a vehicle status detection unit, a plurality of steering switches for performing an operation on controlled in-vehicle equipment, and a memory, when an operational instruction given via the plurality of steering switches is detected, a signal corresponding to the operational instruction is output to the in-vehicle equipment, and the operational instruction is stored in the memory. Subsequently, when an operational instruction given via one of the plurality of steering switches is detected, it is determined, on the basis of information from the vehicle status detection unit, whether a vehicle is being steered. When it is determined that the vehicle is being steered, a signal corresponding to an operational instruction that has been stored just before in the memory is output to the in-vehicle equipment.

Claims

1. An in-vehicle equipment control apparatus comprising:

a vehicle status detection device that detects the status of a vehicle;

an operation device that includes a plurality of controls that are provided on a steering wheel of the vehicle and are used to perform an operation on controlled equipment provided in the vehicle;

a storage device; and

a control device that detects an operational instruction given via the plurality of controls, outputs a signal corresponding to the operational instruction to the controlled equipment, and stores the operational instruction in the storage device,

wherein, in a case where the control device detects a first operational instruction given via one of the plurality of controls, when the control device determines, on the basis of information from the vehicle status detection device, that the vehicle is being steered, the control device outputs a signal corresponding to an operational instruction that has been stored just before in the storage device to the controlled equipment.

2. The in-vehicle equipment control apparatus according to claim 1, wherein, when the control device determines that the vehicle is being steered, the control device does not store the first operational instruction in the storage device.

3. The in-vehicle equipment control apparatus according to claim 1, wherein, in a case where the control device detects the first operational instruction given via the one of the plurality of controls, when the control device determines, on the basis of information from the vehicle status detection device, that the vehicle is not being steered, the control device outputs a signal corresponding to the first operational instruction to the controlled equipment.

4. The in-vehicle equipment control apparatus according to claim 1, wherein the vehicle status detection device includes a steering angle sensor that detects a steering angle of the steering wheel and a shift position sensor that detects a position of a shift of the vehicle, and

when the steering angle of the steering wheel detected by the steering angle sensor is equal to or more than a predetermined angle and when the position of the shift of the vehicle detected by the shift position sensor is other than parking and neutral, the control device determines that the vehicle is being steered.

5. The in-vehicle equipment control apparatus according to claim 1, wherein the vehicle status detection device includes a steering angle sensor that detects a steering angle of the steering wheel and a parking brake sensor that detects whether a parking brake of the vehicle is applied, and

when the steering angle of the steering wheel detected by the steering angle sensor is equal to or more than a predetermined angle and when the status of the parking brake of the vehicle detected by the parking brake sensor is that in which the parking brake is not applied, the control device determines that the vehicle is being steered.

6. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes a vehicle-surrounding image supply unit that displays, on a screen of a display device, images obtained by a plurality of image pickup devices provided so that images around the vehicle can be obtained, and

the plurality of controls includes an image changeover switch for switching from an image from one of the image pickup devices that is displayed on the screen of the display device to an image from another one of the image pickup devices.

7. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes a radio receiver, and

the plurality of controls includes at least one of a station changeover switch for switching from a station that is being received by the radio receiver to another station and a volume changeover switch for changing the volume of a broadcast that is being received by the radio receiver.

8. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes a television receiver, and

the plurality of controls includes at least one of a station changeover switch for switching from a station that is being received by the television receiver to another station and a volume changeover switch for changing the volume of a broadcast that is being received by the television receiver.

9. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes a CD player, and

the plurality of controls includes at least one of a track changeover switch for switching from a track of a CD that is being played back by the CD player to another track and a volume changeover switch for changing the volume of a track that is being played back by the CD player.

10. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes a DVD player, and

the plurality of controls includes at least one of a chapter changeover switch for switching from a chapter of a DVD that is being played back by the DVD player to another chapter and a volume changeover switch for changing the volume of a chapter that is being played back by the DVD player.

11. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes different AV units, and

the plurality of controls includes a source changeover switch for switching from an operating one of the AV units to another one of the AV units.

12. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes an air conditioner, and

the plurality of controls include at least one of a temperature changeover switch for changing a temperature set in the air conditioner and an air volume changeover switch for changing an air volume set in the air conditioner.

13. The in-vehicle equipment control apparatus according to claim 1, wherein the controlled equipment includes a speech recognition unit that performs speech recognition on speech by a user input through a speech input device provided in the vehicle and performs control corresponding to the recognized speech on another component of the controlled equipment, and

the plurality of controls includes a switch for instructing the speech recognition unit to perform speech recognition on speech by the user.

14. A method for controlling controlled equipment provided in a vehicle in an in-vehicle equipment control apparatus that includes a vehicle status detection device that detects the status of the vehicle, an operation device that includes a plurality of controls that are provided on a steering wheel of the vehicle and are used to perform an operation on the controlled equipment, and a storage device, the method comprising:

when an operational instruction given via the plurality of controls is detected, outputting a signal corresponding to the operational instruction to the controlled equipment and storing the operational instruction in the storage device;

subsequently, when a first operational instruction given via one of the plurality of controls is detected, determining, on the basis of information from the vehicle status detection device, whether the vehicle is being steered; and

when it is determined that the vehicle is being steered, outputting a signal corresponding to an operational instruction that has been stored just before in the storage device to the controlled equipment.

15. The method according to claim 14, wherein, when the first operational instruction given via the one of the plurality of controls is detected, it is determined, on the basis of information from the vehicle status detection device, whether the vehicle is being steered, and when it is determined that the vehicle is not being steered, a signal corresponding to the first operational instruction is output to the controlled equipment.
