Problems solved by technology

[0005] Compared with braking force control devices represented by anti-lock braking system (ABS) or dynamic stability control system (DSC), the electric parking brake device has a lower operating response, so there is a possibility that the driver may press the accelerator pedal. When pedaling, the electric parking brake device causes a delay in the complete release of the wheel braking force, and there is concern that the starting performance of the vehicle will decrease;

Embodiment 1

[0058] The following is based on Figure 1 to Figure 5 Embodiment 1 illustrating the present invention;

[0059] Such as figure 1 , figure 2 As shown, the vehicle V is equipped with a stop maintaining device 1;

[0060]The stop maintaining device 1 includes: a foot brake device 2 (foot brake mechanism), a DSC (Dynamic Stability Control System) device 3 (braking force control mechanism), an EPB (Electric Parking Brake) device 4 (electric parking brake mechanism), an ECU ( Electronic Control Unit) 10 (control department), etc.

[0061] First illustrate the foot brake device 2;

[0062] The foot brake device 2 is formed so that the brake fluid (hereinafter referred to as brake fluid pressure) pressurized by stepping on the brake pedal 5 is supplied to the two pairs of front and rear hydraulic brake mechanisms 20 , so that the two pairs of front and rear wheels 6 can be braked. Structure;

[0063] Such as figure 1 , image 3 As shown, the foot brake device 2 has a brake p...

Abstract

A vehicle stop maintaining system is provided, which includes a foot brake mechanism for braking vehicle wheels by applying hydraulic brake pressure according to brake pedal depression, a brake force control mechanism for braking the wheels by controlling a pressurizer, an electric parking brake mechanism for braking the wheels by operating an electric brake mechanism, and a controller comprising a processor for entering a first stop mode when a vehicle stopped state is detected. The processor executes a first determining module for determining existence of an interruptive factor, and a second determining module for determining a failure of the electric parking brake mechanism. If the interruptive factor exists, the controller executes a second stop mode. If the electric parking brake mechanism is determined as failed under the second stop mode, the controller operates a notification device for issuing a notification to a vehicle driver.

Description

technical field [0001] The present invention relates to a vehicle stop maintaining device, and more particularly to a vehicle stop maintaining device capable of maintaining a stopped state by operating a braking force control device when a vehicle is stopped. Background technique [0002] Conventionally, there are known brake devices for vehicles: a foot brake device that supplies brake hydraulic pressure corresponding to the stepping operation of the brake pedal to a hydraulic brake mechanism to brake wheels; A pressurizing part that pressurizes the brake hydraulic pressure and controls the pressurizing part independently of the stepping operation of the brake pedal so as to be able to brake the braking force control device of the wheel; An electric parking brake device in which the electric brake mechanism driven by an actuator operates to brake the wheels; [0003] In addition, when the stopped state of the vehicle is detected, the electric parking brake device is activa...
