A vehicle periphery monitoring apparatus displays a mobile object on a display unit, encircled by a detection frame, which notifies the driver of the vehicle concerning the presence of the mobile object. A mobile object detector judges a travel path of the mobile object, and a display processor changes an area within which the detection frame is not displayed, depending on the direction in which the judged travel path extends. The detection frame is displayed only when necessary, so as to indicate the presence of the mobile object to the driver using the detection frame.

Vehicle periphery monitoring apparatus

A brake system for a vehicle includes an electrically operated parking brake drive device which generates an operating force for operating the wheel brakes or dedicated parking brakes in response to energization, and which operates even upon cancellation of the energization while in the operated state. A braking force related amount detector detects a physical quantity related to a braking force exhibited by each of the hydraulic pressure operated wheel brakes. When a detected physical quantity exceeds a reference value in a stopped state of the vehicle, a controller energizes the electrically operated parking brake drive device. Thus, the frequency of operation of the electrically operated parking brake drive device is decreased while eliminating inconvenient operations required to operate the electrically operated parking brake drive device, thereby reducing noise and improving durability.

Brake system for vehicle

When a shift position is shifted from an R range to a D range and when the shift position is shifted from the D range to the R range, an electrically-operated parking brake device is automatically cancelled. In this manner, the electrically-operated parking brake device is cancelled without waiting for the depression of an accelerator pedal with a driver's intention to start a vehicle taken into consideration. Therefore, it is possible not only to alleviate a burden on the driver in canceling the electrically-operated parking brake device, but also to prevent an abrupt starting of the vehicle due to the cancellation of the electrically-operated parking brake device while the accelerator pedal is being depressed to transmit a large driving force to driven wheels.

Electrically-operated parking brake device

An electric parking brake system that includes a parking brake, and an electric motor, wherein the parking brake is activated by the electric motor. Operation of the parking brake is controlled such that a vehicle is decelerated at a target deceleration of a predetermined magnitude when an operation command to operate the parking brake is issued by a driver via an operation switch while the vehicle is running. If a service brake fails while a vehicle is running, when the driver depresses the operation switch to issue the operation command to a parking brake to brake the vehicle, the parking brake is controlled such that the vehicle is decelerated at the target deceleration of the predetermined magnitude set on the basis of the number of times of depressing the operation switch.

Electric parking brake system

A vehicle brake control system includes an improved ACC system for controlling the operation of a brake actuator and a throttle actuator, based on a signal from a preceding vehicle detector such as a radar device, so that a subject vehicle tracks a preceding vehicle. After a regular brake device is actuated to stop the subject vehicle, an EPB ECU disengages the regular braking device and, instead, actuates an electrically initiated and mechanically maintained parking brake device, so as to temporarily maintain the subject vehicle in a stationary state. Once the electric parking brake device is initiated, its braking state is mechanically maintained even if the flow of current is cut off. Therefore, neither the regular brake device nor the electric parking device consume power while the vehicle is in a stationary state, thereby saving power and minimizing electrical heat generation.
