Fault-tolerant automotive braking system
A vehicle includes a fault-tolerant braking system that controls a brake assembly which is configured to adjust a braking force applied to one or more wheels. The fault-tolerant braking system further includes a brake-by-wire (BBW) system and a vehicle control module (VCM). The BBW system is configured to control the brake assembly in response to a braking request. The VCM is configured to detect a fault of at least one of the brake assembly and the BBW system. In response to detecting the fault, the VCM selectively operates the vehicle between a normal operating mode and at least one degraded driving mode that limits operation of at least one of the vehicle engine and the vehicle transmission compared to the normal operating mode.
Method and control system for controlling machine
A method for controlling a machine during a transition from a service brake state to a parking brake includes receiving, by a control module, a request for activating a parking brake assembly. The method also includes transmitting, by the control module, control signals for activating a set of first brakes associated with a service brake assembly, a set of second brakes associated with the service brake assembly, and a clutch assembly. The method further includes controlling, by the control module, the set of first brakes for deactivating the set of first brakes. The method includes controlling, by the control module, the parking brake assembly for activating the parking brake assembly. The method also includes controlling, by the control module, the set of second brakes for deactivating the set of second brakes. The method further includes controlling, by the control module, the clutch assembly for deactivating the clutch assembly.
