A method of diagnosing an electrically operated brake for abnormality thereof in an automotive vehicle wherein a wheel is braked by a friction force generated by an electric motor of the brake upon an operation of a brake operating member, the method comprising the steps of: applying an abnormality checking drive signal to the electric motor to operate the electric motor while the brake operating member is placed in a non-operated position; detecting a quantity relating to an output of the electric motor while the drive signal is applied to the electric motor; and determining that the electrically operated brake is abnormal, if the detected quantity does not normally correspond to a magnitude of the abnormality checking drive signal.
A method of diagnosing an electrically operated brake for abnormality thereof in an automotive vehicle wherein the brake includes an electric motor as a drive source for generating a friction force upon an operation of a manually operated brake operating member, to brake a wheel of the vehicle, said method comprising the steps of:
A method of diagnosing an electrically operated brake for abnormality thereof in an automotive vehicle having a drive power source, a manually operated vehicle accelerating member for increasing an output of the drive power source for accelerating the automotive vehicle, a manually operated normal brake operating member for operating an electric motor of said electrically operated brake to generate a friction force for braking a wheel of the automotive vehicle, a parking brake, and a manually operated parking brake operating member for activating said parking brake to apply a parking brake to said wheel, and wherein a creep torque is applied from said drive power source to said wheel for slowly starting said automotive vehicle while said vehicle accelerating member is placed in a non-operated position, said method comprising the steps of:
A braking system for an automotive vehicle comprising an electrically operated braking device including (a) a manually operated brake operating member, (b) a braking member having a rotor rotating with a wheel of the vehicle and a friction member which is forced onto said rotor to brake said wheel, (c) an electric motor, (d) a drive force transmitting device for transmitting a drive force of said electric motor to said friction member, (e) an operation amount sensor for detecting an amount of operation of said brake operating member, and (f) a motor controller for controlling said electric motor on the basis of an output of said operation amount sensor, said braking system further comprising:
A braking system for an automotive vehicle, comprising a drive power source, a manually operated vehicle accelerating member for increasing an output of the drive power source for accelerating the automotive vehicle, an electrically operated brake, a manually operated normal brake operating member for operating an electric motor of said electrically operated brake to generate a friction force for braking a wheel of the automotive vehicle, a parking brake, and a manually operated parking brake operating member for activating said parking brake to apply a parking brake to said wheel, said automotive vehicle being arranged such that a creep torque is applied from said drive power source to said wheel for slowly starting said automotive vehicle while said vehicle accelerating member is placed in a non-operated position thereof, said braking system further comprising:
