Estimating the term…
A motor vehicle (10) has wheels (22F, 22R) on which it travels, a powertrain (12) for delivering propulsion torque to at least some of the wheels to propel the vehicle, and a service brake system (24) having service brakes (28). When the service brakes are applied by a service brake actuator (26), braking torque is applied to at least some of the wheels. A first device (36) provides data representing a velocity that correlates with velocity of the vehicle, and a second device (38) associated with the actuator provides data that distinguishes between application and non-application of the service brakes by the actuator. A processor (34) monitors data from the first and second devices and processes the monitored data (FIG. 2) to provide a data output BPP_FLT when the first device has disclosed velocity change indicative of the service brakes having been applied without the second device having disclosed that the service brakes have been applied.
A motor vehicle comprising:
A motor vehicle diagnostic system for signaling that a first device has disclosed vehicle velocity change indicative of service brakes of the vehicle having been applied without a second device having disclosed that an actuator for actuating the service brakes has been operated, the system comprising in combination with the first and second devices:
A method for signaling that a first device in a motor vehicle has disclosed vehicle velocity change indicative of service brakes of the vehicle having been applied without a second device in the vehicle having disclosed that an actuator for actuating the service brakes has been operated, the method comprising:
