  • Publication number: 20240140411
    Abstract: A vehicle control apparatus executes a collision avoidance control when a collision condition becomes satisfied. The collision condition includes a condition that a lap rate of the own vehicle and the object is equal to or greater than a lap rate threshold. The threshold set when the own vehicle turns, is greater than the threshold set when the own vehicle does not turn. The threshold set when a condition satisfaction period of time is equal to or greater than a predetermined period of time, is smaller than the threshold set when the condition satisfaction period of time is smaller than the predetermined period of time. The condition satisfaction period of time is a period of time that a collision probability condition continues being satisfied while the own vehicle is turning. The collision probability condition is a condition that the own vehicle has a probability of colliding with the object.

  • Publication number: 20240101093
    Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.

  • Publication number: 20240075915
    Abstract: A vehicle brake system includes a first fluid pressure generating device for generating a fluid pressure according to a brake operating amount, a second fluid pressure generating device for generating a fluid pressure by moving a piston with an electric actuator, and a switching valve switchable between a first state allowing communication between the first fluid pressure generating device and a vehicle behavior stabilizing device and a second state allowing communication between the second fluid pressure generating device and the vehicle behavior stabilizing device. A control device places the switching valve in the second state during execution of automatic brake control, and places the switching valve in the first state when a predetermined abnormality occurs in the vehicle, except that the control device places the switching valve in the second state when an abnormality including inability of the second fluid pressure generating device to generate the fluid pressure occurs.

  • Publication number: 20230406405
    Abstract: A control device for a vehicle equipped with a steering system including a steering wheel (13), a rack (12) for steering the wheels (4) of the vehicle, and a redundant arrangement for transmitting a displacement of the steering wheel to the rack, wherein upon detecting a failure in the redundant arrangement, the control device sets an upper limit speed to a first value in a first stage, and changes the upper limit speed from the first value to a second value smaller than the first value in a progressive manner in a second stage that follows the first stage.
