    Abstract: A controller sets a target hydraulic pressure of a master cylinder based on the operation amount of a brake pedal, and controls the action of an electric motor so that a master cylinder hydraulic pressure attains the target hydraulic pressure. A brake characteristic representing a relationship between a motor rotation position detected by a resolver and the master cylinder hydraulic pressure as detected by the hydraulic pressure sensor is stored and updated. When the hydraulic pressure sensor is abnormal, a target motor rotation position corresponding to the target hydraulic pressure is set using the updated brake characteristic, and the action of the electric motor is controlled. The electric motor is controlled based on the updated brake characteristic, and hence fluctuations in the vehicle deceleration with respect to the brake operation can be suppressed and a sense of discomfort for the driver can be alleviated.

  • Patent number: 8775064
    Abstract: A method and tools for virtually aligning object detection sensors on a vehicle without having to physically adjust the sensors. A sensor misalignment condition is detected during normal driving of a host vehicle by comparing different sensor readings to each other. At a vehicle service facility, the host vehicle is placed in an alignment target fixture, and alignment of all object detection sensors is compared to ground truth to determine alignment calibration parameters. Alignment calibration can be further refined by driving the host vehicle in a controlled environment following a leading vehicle. Final alignment calibration parameters are authorized and stored in system memory, and applications which use object detection data henceforth adjust the sensor readings according to the calibration parameters.

  • Patent number: 8744678
    Abstract: An apparatus that restricts or disables electronic device functionality based on vehicle status data received from the on-board computer (“OBD”) of a public service vehicle. In some embodiments, the vehicle status data is accessed from the OBD through an assembly line diagnostic link (“ALDL”) connector, which eliminates any need for modification of the vehicle during installation. If the software determines the vehicle status data is outside a preset range, which could be customized on a case-by-case basis, the on-board computer of the vehicle could be restricted or disabled until the vehicle status data returns to within the preset range.

  • Patent number: 8738219
    Abstract: A controller for indicating whether a previously-detected, acceleration-sensor malfunction no longer exists. The controller includes an electronic memory and an electronic processing unit connected to the electronic memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The signal checking module performs a signal check after the malfunction monitoring module generates the fault signal. The signal check includes executing a signal check function with a longitudinal acceleration signal. Also disclosed is a vehicle including the controller, and a method executed by the controller.

  • Patent number: 8670899
    Abstract: A method for detection of a control event by a sensor arrangement having at least one sensor element and a sensor controller is described. The sensor controller digitizes sensor signals into sensor measured values. An operator control event is produced by a user and a first coarse evaluation for a sign of operator control is performed and a predetermined number of sensor measured values are progressively buffer-stored in a buffer store wherein detection of a sign of operator control initiates a fine evaluation of the sensor measured values to verify the occurrence of an operator control event at an initiation time. The fine evaluation is based on the buffer-stored sensor measured values and on subsequent sensor measured values, so that the fine evaluation includes sensor measured values both before and after the initiation time.
