Abstract
Operation of a vehicle, such as a tractor-trailer, is prevented or modified if operation of the vehicle would be dangerous or destructive due to a brake system abnormality. A motor controller limits the speed of a moving vehicle if a brake system reservoir pressure is below a predetermined threshold or if parking brakes are applied. Additionally, if there is a brake system abnormality, the motor controller limits the motor torque produced in a stationary or slowly moving vehicle. Electronically controlled brake system control modules are recruited to monitor brake system status information and report abnormalities to the motor controller. Preferably, the electronically controlled brake control modules communicate with the motor controller over a serial link.
