Operator intent based passive keyless vehicle control system
First Claim
1. A method for operating a device on a motor vehicle using a system which includes a remote control carried by a driver and a control circuit in the motor vehicle, said method comprising the steps of:
- the remote control occasionally, automatically transmitting a command signal;
the control circuit, upon receiving the command signal, sensing an action by the driver which indicates an intention to operate the device, andsending an activation signal to the device in response to sensing the action by the driver.

Abstract
A passive remote operating system is disclosed which may be employed to gain entry to a vehicle. A remote control, carried by a driver, periodically transmits a command signal whenever the remote control is moving. As the driver approaches the vehicle, the remote control comes within the reception range of a control circuit in the vehicle, which then receives the command signal. Receipt of the command signal activates the control circuit to begin sensing for an action by the driver, such as operation of a door handle, which indicates an intention to enter the vehicle. Upon sensing that action within a given period after receipt of the command signal, the doors of the vehicle are unlocked.

11. An apparatus for operating a device on a motor vehicle, the apparatus comprising:
-
a remote control adapted to be carried by a driver, the remote control occasionally, automatically transmitting a command signal; a receiver on the vehicle to receive the command signal from the remote control and in response produce a receiver signal; a sensor on the vehicle to detect an action by the driver which indicates an intention to operate the device and in response produce a sensor signal; and controller in the motor vehicle and connected to the sensor, the receiver and the device, the controller upon receiving the receiver signal and the sensor signal sends an activation signal to the device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
