  • Patent number: 10576983
    Abstract: A vehicle system comprises a brake system comprising a brake pedal and a braking mechanism configured to apply a braking force to a vehicle, and a vehicle control unit operable to automatically stop an engine when the vehicle is decelerated to a given vehicle speed or less during traveling. When it is detected that the brake pedal is manipulated and the vehicle is stopped after automatically stopping the engine, the vehicle control unit is operable to control the braking mechanism to increase the braking force from a current value according to a manipulation amount of the brake pedal up to a given value.

  • Patent number: 10358120
    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.

  • Patent number: 10322706
    Abstract: A vehicle stop maintaining system is provided, which includes a foot brake mechanism, a brake force control mechanism having a pressurizer and for braking the vehicle wheels by controlling the pressurizer independently from depression of a brake pedal, a controller for maintaining a vehicle stopped state by operating the brake force control mechanism when the stopped state is detected, and operating an automatic stop control, an automatic stop mode switch for selecting ON/OFF states of the automatic stop control upon receiving an input from a vehicle driver, and a control mechanism for controlling a given mechanism that is different from the brake force control mechanism, and operating the brake force control mechanism in response to a given operation by the driver. When the given operation is performed on the control mechanism by the driver, the controller switches the selected one of the ON/OFF states to the other state.

  • Publication number: 20170151936
    Abstract: A vehicle stop maintaining system comprises a foot brake mechanism for braking vehicle wheels by applying hydraulic brake pressure to hydraulic brake mechanisms according to a depression of a brake pedal, a brake force control mechanism having a pressurizer that increases hydraulic brake pressure to be applied to the hydraulic brake mechanisms, braking the wheels by controlling the pressurizer independently from the depression of the brake pedal, and a controller for executing, when the vehicle is detected to be in a stopped state, a first stop mode in which the brake force control mechanism is operated to maintain the stopped state. The system includes a gear position detector for detecting a position of a gear shift lever of the vehicle. When a vehicle driver intentionally controls the gear shift lever to a reverse position in the first stop mode, the controller cancels the first stop mode.
