  • Patent number: 11014554
    Abstract: In a vehicle control apparatus, an object recognizing block recognizes an object which is present around a vehicle. In cases where there is a possibility that the vehicle will collide with an object recognized by the object recognizing block, the apparatus performs automatic braking control which brakes the vehicle. If the driver depresses the accelerator pedal in a predetermined depressing state, a braking controlling block cancels the automatic braking control. When an operation determining block determines that there is a driver's predetermined shift-lever position change, with which the driver's predetermined shift-lever position change is carried out during a driver's accelerator pedal depressing operation, the braking controlling block responds to a driver's accelerator depressing operation by not cancelling the automatic braking control or by making cancellation of the automatic braking control more difficult.

  • Patent number: 10899324
    Abstract: A braking control device generates a force for pressing a friction member against a rotating member fixed to a wheel of the vehicle via an electric motor controlled by a controller in accordance with an operation amount of an operation member. A pressing force sensor detects a pressing force actual value, and a rotation angle sensor detects a rotation angle actual value of the motor. The controller determines whether an operating state of the pressing force sensor is appropriate. When the operating state is appropriate, the motor output is adjusted based on the pressing force actual value, a correlation between the pressing force actual value and the rotation angle actual value is stored, and a conversion calculation map is created based on the correlation. When the operating state is not appropriate, the motor output is adjusted based on the rotation angle actual value and the conversion calculation map.

    Abstract: A braking control device comprising: an operation amount acquisition device that obtains an operation amount for a braking operation member; a pressurizing unit that presses a friction member to a rotating member fixed to a wheel, by using an electric motor; a control that controls the output of the motor based on the operation amount; a pressing force acquisition device that obtains the actual pressing force of the friction member pressing on the rotating member; and a rotation angle acquisition device that obtains the actual rotation angle of the motor. The control: stores the correlation between the actual pressing force and the actual rotation angle; approximates a function map indicated by a second degree or higher polynomial based on the correlation; calculates a target rotation angle based on the operation amount and the function map; and controls the motor such that the actual rotation angle matches the target rotation angle.

  • Patent number: 10899331
    Abstract: A hydraulic actuator for supplying a hydraulic brake pressure to service brakes of a vehicle includes an actuator cylinder including a piston. A hydraulic working pressure of a brake fluid can be set in accordance with a position of the piston. The brake fluid is supplied from a hydraulic reservoir assigned to the hydraulic cylinder, and the hydraulic working pressure prevails in a working space of the actuator cylinder and can be output via an actuator output port on the actuator cylinder in order to supply a hydraulic brake pressure in accordance with the hydraulic working pressure. The hydraulic actuator further includes an electrically controllable motor. A rotary motion brought about by the electrically controllable motor can be converted by a conversion mechanism into a translational motion of the piston parallel to a longitudinal direction thus enabling a hydraulic brake pressure to be supplied by electric control of the motor.

  • Patent number: 10850717
    Abstract: A driving assistance apparatus determines, based on an instantaneous indicator which is an instantaneous value of a parameter regarding steering of the own vehicle, whether a driver has started a collision avoidance operation for avoiding a collision between a target and the own vehicle. When it is determined that the collision avoidance operation has been started, a support start timing for starting driving assistance for avoiding the collision between the target and the own vehicle or reducing collision damage is set to be a timing later than when the collision avoidance operation has not been started. The support start timing during a collision avoidance time period which is a time period until a predetermined set time has elapsed after it is determined that the collision avoidance operation has been started is set based on a time-dependent indicator for steering indicated by the instantaneous indicator at timings during the collision avoidance time period.
