Patent
CA 2031877
A safety method is provided for use with control systems for vehicles such as trucks, and in particular for electromechanical controls (10) that assist the driver in shifting the gears (12), operating the clutch (16), and in actuating the throttle (22, 24, 26) by remote control. The method, which is for use in a vehicle's throttle-actuator subsystem (26A), utilizes a transmission control processor (42A) and a throttle control processor (42B). The method ascertains whether, when the driver of the vehicle removes his foot from the accelerator pedal (24A), control of the fuel pump (26C) returns to the idle governor as it should. The flow of fuel is stopped if it does not return properly. Also, a method is provided that monitors the throttle actuator (26A) to insure that it accurately follows throttle commands such as the position of the accelerator pedal (24A).
