Abstract

A vehicle system includes a sensor and a processing device. The sensor is configured to detect an impact vehicle. The processing device is programmed to predict an impact zone, define a passenger zone relative to a host vehicle, and generate a control signal to move the impact zone away from the passenger zone. The passenger zone is defined at least in part on a location of at least one occupant inside the host vehicle.

Claims

1. A vehicle system, for use in a host vehicle, the vehicle system comprising:

a sensor configured to detect an impact vehicle; and

a processing device programmed to predict an initial impact zone defining an impact location relative to the host vehicle, define a passenger zone relative to the host vehicle, predict a plurality of future impact zones based on a simulated acceleration and deceleration of the host vehicle, select one of the plurality of future impact zones that moves the impact location furthest away from the passenger zone, and either accelerate or decelerate the host vehicle by actuating an accelerator pedal or a brake pedal, respectively, in accordance with the selected future impact zone to move the impact location furthest away from the passenger zone,

wherein the passenger zone includes at least one area of a passenger compartment in the host vehicle with at least one detected occupant and excludes areas of the passenger compartment where no occupants are detected.

2. The vehicle system of claim 1, further comprising an occupant detection system configured to determine a location of the at least one occupant, wherein the processing device is programmed to define the passenger zone in accordance with a signal output by the occupant detection system.

3. The vehicle system of claim 1, wherein the processing device is programmed to generate a control signal to either accelerate or decelerate the host vehicle to move the impact zone away from the passenger zone.

4. The vehicle system of claim 1, wherein the passenger zone includes a driver seat area corresponding to a location of a driver seat in the host vehicle.

5. The vehicle system of claim 1, wherein the passenger zone includes at least one of a passenger seat area corresponding to a location of a passenger seat in the host vehicle, a first rear seat area corresponding to a location of a first rear seat in the host vehicle, and a second rear seat area corresponding to a location of a second rear seat in the host vehicle.

6. The vehicle system of claim 1, wherein the processing device is programmed to generate a control signal in accordance with a powertrain characteristic of the host vehicle.

7. The vehicle system of claim 1, wherein the processing device is programmed to generate a control signal in accordance with a braking characteristic of the host vehicle.

8. The vehicle system of claim 1, wherein the processing device is programmed to receive a driver input signal and determine whether the driver input signal controls the host vehicle to move the impact zone away from the passenger zone.

9. The vehicle system of claim 8, where in the processing device is programmed to override the driver input signal with the control signal in response to determining that the driver input signal controls the host vehicle to keep the impact zone inside of the passenger zone.

10. A method, for use in a host vehicle, the method comprising:

detecting an impact vehicle;

determining an initial impact zone defining an impact location relative to the host vehicle;

defining a passenger zone relative to the host vehicle, wherein the passenger zone includes an area of a passenger compartment in the host vehicle with at least one detected occupant and excludes areas of the passenger compartment where no occupants are detected;

predicting a plurality of future impact zones based on a simulated acceleration and deceleration of the host vehicle;

selecting one of the plurality of future impact zones that moves the impact location furthest away from the passenger zone; and

accelerating or decelerating the host vehicle by actuating an accelerator pedal or a brake pedal, respectively, in accordance with the selected future impact zone prior to the impact vehicle colliding with the host vehicle to move the impact location furthest away from the passenger zone.

11. The method of claim 10, further comprising determining a location of the at least one occupant inside the host vehicle.

12. The method of claim 10, further comprising generating a control signal to either accelerate or decelerate the host vehicle.

13. The method of claim 10, further comprising generating a control signal in accordance with at least one of a powertrain characteristic and a braking characteristic of the host vehicle.

14. The method of claim 10, further comprising:

receiving a driver input signal; and

determining whether the driver input signal controls the host vehicle to move the impact zone away from the passenger zone.

15. The method of claim 14, further comprising overriding the driver input signal with the control signal in response to determining that the driver input signal controls the host vehicle to keep the impact.

16. A vehicle system, for use in a host vehicle, the vehicle system comprising:

an occupant detection system configured to determine a location in a passenger compartment of at least one occupant in the host vehicle;

a sensor configured to detect an initial impact vehicle; and

a processing device programmed to predict an impact zone defining an impact location relative to the host vehicle, define a passenger zone relative to the host vehicle in accordance with a signal output by the occupant detection system, predict a plurality of future impact zones based on a simulated acceleration and deceleration of the host vehicle, select one of the plurality of future impact zones that moves the impact location furthest away from the passenger zone, and either accelerate or decelerate the host vehicle by actuating an accelerator pedal or a brake pedal, respectively, in accordance with the selected future impact zone to move the impact location furthest away from the passenger zone,

wherein the passenger zone includes at least one area of the passenger compartment in the host vehicle with at least one detected occupant and excludes areas of the passenger compartment where no occupants are detected, and

wherein the processing device is programmed generate a control signal to either accelerate or decelerate the host vehicle and wherein the control signal is generated in accordance with at least one of a powertrain characteristic and a braking characteristic of the host vehicle.

17. The vehicle system of claim 16, wherein the passenger zone includes at least one of a driver seat area corresponding to a location of a driver seat in the host vehicle, a passenger seat area corresponding to a location of a passenger seat in the host vehicle, a first rear seat area corresponding to a location of a first rear seat in the host vehicle, and a second rear seat area corresponding to a location of a second rear seat in the host vehicle.
