Abstract
A process for determining a stationary state of a vehicle includes providing a camera and a control having an image processor. Vehicle data is provided to the control by an accelerometer of the vehicle and by at least one of (i) a transmission sensor of the vehicle and (ii) a speed sensor of the vehicle. A determination that the vehicle is stationary is made when at least one of (i) the control determines a jerk value that is approximately zero for a selected duration of time and the control receives vehicle data indicating that the speed of the vehicle was approximately zero for the selected duration of time and (ii) the control determines a jerk value that is approximately zero for a selected duration of time and the control receives vehicle data indicating that the transmission of the vehicle was in ‘Park’ for the selected duration of time.
