Vehicle control device
A vehicle control device is mounted on a vehicle including a driving actuator configured to apply a driving force and a braking actuator configured to apply a braking force. The vehicle control device includes a processor. The processor is configured to correct, when a predetermined condition including at least that the vehicle is decelerating is satisfied, the required driving force and the required braking force so as to increase the required driving force and the required braking force such that a sum of a magnitude of the required driving force and a magnitude of the required braking force is equal to or larger than a magnitude of the component of the gravity acting on the vehicle in the movement direction of the vehicle.
METHOD AND APPARATUS FOR CONTROLLING ELECTRO-MECHANICAL BRAKE
An electro-mechanical brake device comprising: a sensor unit comprising one or more sensors; an electronic parking brake (EPB) configured to fix a wheel of the vehicle when the vehicle is parked; a hydraulic braking unit configured to supply a braking force to a wheel brake using hydraulic pressure generated at a master cylinder; a driving control unit configured to determine whether braking is required for the vehicle based on at least one of a driver's braking intention, a change in the hydraulic pressure at the master cylinder, a vehicle status, an engine status and a transmission state, and further configured to determine whether an actuator has failed; and an actuator decision unit configured to, when the driving control unit determines that braking is required for the vehicle, brake the vehicle using any one of the hydraulic braking unit and the EPB depending on whether the actuator has failed.
Automated system and method for parking a commercial vehicle
A system for automatically parking a commercial vehicle comprises a service brake system having at least one braking valve, a braking controller for controlling the service brake system, and an advanced driver assistance system (ADAS) controller. The ADAS controller communicates with the braking controller and requests activation of the service brakes of the commercial vehicle until the vehicle is stationary. The braking controller, in response to the ADAS controller requesting activation of the service brakes, determines the commercial vehicle should remain stationary and activates at least one braking valve to exhaust system pressure to mechanically park the vehicle.
Parking braking force-associated remote start-up method and remote start-up system of manual transmission vehicle
A remote start-up method of a manual transmission vehicle is provided. The method includes a parking braking force-associated remote start-up control that remotely starts-up an inclined parking vehicle parked on a ramp by confirming a situation where the parking braking force is maintained by a braking hydraulic pressure control of an electronic stability control (ESC) system in a remote start-up controller.
Parking brake apparatus and method therefor
A parking brake apparatus for a vehicle includes a parking brake controller controlling a parking brake system and arranged to obtain one or more input signals indicative of one or more actions from one or more vehicle systems other than the parking braking system. The parking brake controller is also arranged to provide one or more control signals to be applied to components of the parking brake system to apply parking brakes based upon an adaptive time delay to prevent a vehicle rollaway when the one or more input signals are indicative of the one or more actions meeting respective one or more predetermined conditions.
Controller and control method
A controller and a control method to a vehicle, the controller and the control method executing brake control in which primary information is selectively supplemented by secondary information that is information on an assumed state related to connection and disconnection of a clutch. The controller includes a determination section that determines whether an actual state and the assumed state, which are related to the connection and the disconnection of the clutch, match each other in accordance with a temporal change in the secondary information; and a brake control section that executes the brake control by using the primary information but not the secondary information in the case where the determination section determines that the actual state and the assumed state do not match each other.
ELECTRONIC PARKING BRAKE SYSTEM AND METHOD OF CONTROLLING THE SAME
Provided is an electronic parking brake system including: an electronic parking brake configured to provide a clamping force required for parking a vehicle by a motor; and a controller electrically connected to the motor, wherein the controller is configured to, in response to the electronic parking brake being in a parking release state or in a parking stop state and a transmission position being in a P-stage, identify whether a rollback occurs in the vehicle, and upon determining that a rollback has occurred in the vehicle, operate the electronic parking brake to park the vehicle.
Control device and control method for executing and canceling hill-hold control
Controller and control method for improving operability at a time when a brake force that is retained in hill-hold control is reduced. A control section for executing the hill-hold control that retains the brake force on an inclined road surface is provided. The control section cancels retention of the brake force in the case where it is determined on the basis of a detection signal of a first detection mechanism that a first operation section for operating a brake mechanism is operated when the brake force is retained in the hill-hold control.
ARRANGEMENT AND METHOD FOR CONTROLLING WORKING BRAKES OF A HYDRAULICALLY OR ELECTRICALLY OPERATED WORK MACHINE

AUTOMATED BRAKING CONTROL SYSTEMS
Systems and methods for controlling a vehicle. One example system includes a deceleration actuator coupled to a first wheel of the vehicle and an electronic processor communicatively coupled to the deceleration actuator. The electronic processor is configured to receive a vehicle park command. The electronic processor is configured to, responsive to receiving the vehicle park command, determine a maximum holding pressure threshold. The electronic processor is configured to determine a requested braking pressure for the deceleration actuator. The electronic processor is configured to determine whether the requested braking pressure exceeds the maximum holding pressure threshold. The electronic processor is configured to, responsive to determining that the requested braking pressure does not exceed the maximum holding pressure threshold, control the deceleration actuator to apply, to the first wheel during a hold time, a holding braking pressure equivalent to the requested braking pressure.
