  • Patent number: 8661884
    Abstract: A stroke sensor abnormality determining apparatus includes a stroke sensor for detecting a stroke of a brake pedal by detecting an electric signal that varies in response to the stroke of the brake pedal, a deceleration calculating unit for calculating a total target value, which is correlated with a target deceleration of a vehicle, based on at least the stroke, and an abnormality determining unit for determining whether or not an abnormality of the stroke sensor occurs, based on the electric signal detected by the stroke sensor, the abnormality determining unit being configured so that a signal indicating the abnormality of the stroke sensor can be outputted when the abnormality is determined to have occurred in the stroke sensor.

  • Patent number: 8412422
    Abstract: A vehicle control apparatus including a brake mechanism that produces braking force through actuation of a first actuator, a shift mechanism that changes the shift position of a transmission through actuation of a second actuator, a controller that controls the electric power supplied to the first actuator and the electric power supplied to the second actuator; a first electric power supply unit that supplies electric power to the controller; a second electric power supply unit that supplies electric power to the first actuator; and a third electric power supply unit that supplies electric power to the second actuator. An actuator control unit controls the electric power supplied to the second actuator from the second electric power supply unit or from the third electric power supply unit when the second actuator is not able to operate using electric power supplied from the first electric power supply unit.

  • Patent number: 8042887
    Abstract: A brake control apparatus for controlling brakes of a vehicle having wheels, the apparatus including a stopped-state detecting portion which detects, based on a speed of at least one of the wheels detected by at least one wheel-speed sensor, a stopped state of the vehicle; an operation-force limiting portion which limits, based on a detection of the stopped state of the vehicle by the stopped-state detecting portion, an operation force of at least one of the brakes, such that an upper limit of the operation force is an intermediate level of an operation-force range used when the stopped state is not detected; a sensor ignoring portion which ignores, when an electric voltage supplied from a power source to the at least one wheel-speed sensor is not higher than a reference value, the at least one wheel-speed sensor; a limitation canceling portion which cancels, when the sensor ignoring portion ignores the at least one wheel-speed sensor, a limitation of the operation force by the operation-force limiting portio
