A control device and method for executing a holding function using a hydraulic braking system of a vehicle including building up an initial holding pressure in at least one wheel brake cylinder using at least one brake pressure buildup device and closing at least one shutoff valve situated between the at least one wheel brake cylinder and the at least one brake pressure buildup device, a new holding pressure being built up in the wheel brake cylinder, in that an intermediate pressure less than the new holding pressure is built up between the shutoff valve and the brake pressure buildup device using the brake pressure buildup device, the shutoff valve is opened upon the presence of the intermediate pressure between the shutoff valve and the brake pressure buildup device, and brake fluid is transferred using the brake pressure buildup device through the open shutoff valve into the wheel brake cylinder.

A method and system include a vehicle control system including a multi-vehicle system. The system includes a controller. The controller determines a slack condition of a multi-vehicle system while the multi-vehicle system is parked. The controller determines the slack condition based on one or more sensor signals received from at least one sensor, the controller configured to control movement of the multi-vehicle system based on the slack condition that is determined while transitioning from being parked to forward motion.

A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.

The assembly comprises a body wherein there are defined a chamber, a supply valve adapted to connect the chamber to a pressure source or to the atmosphere, and a vent valve adapted to allow or prevent the connection of the chamber to the atmosphere. The valves are provided with control solenoids to which respective electronic switches are coupled. The assembly also comprises electronic control devices adapted to provide, as a function of the values of at least one input signal, logic control signals to the electronic switches so as to control, through the valves, the value of the pressure in the chamber. The control means comprise two processing and control devices independent of one another, both receiving the input signal and designed to execute strategies for controlling the pressure in the chamber, equivalent to one another.

A motorcycle (300) includes a clutch lever (14), a clutch switch (15) configured to detect whether or not the clutch lever (14) is gripped, a vehicle speed sensor (16) configured to detect a vehicle speed, a hydraulic rear brake (18), a pressurizing unit (17) configured to perform a pressurizing process that applies an oil pressure to the rear brake (18), and a microcontroller (19) configured to control the pressurizing process by the pressurizing unit (17) based on results of the detection by the vehicle speed sensor (16) and the clutch switch (15).

A four wheel steering vehicle (1), in which front wheels (2f) and rear wheels (2r) can be steered in response to a steering input from a steering wheel (11), includes a rear wheel steering control unit (50) that variably controls a rear wheel steering device such that the rear wheels are steered in a prescribed relation to a steered angle of the front wheels. When the steering input is determined while the front wheel brake and the rear wheel brake are engaged, the rear wheel steering control unit disengages the rear wheel brake and steers the rear wheels. When the fore and aft inclination angle detected by an inclination sensor (40) provided on the vehicle is greater than a threshold value, the rear wheel steering control unit prohibits a steering of the rear wheels and keeps the rear wheel brake engaged even if the steering input is determined.

A control device configured to control a vehicle is provided. The device comprises: a traveling control unit capable of executing stop hold control in an automatic brake hold function and a one-pedal function; and an output control unit capable of displaying a first indicator indicating that the one-pedal function is enabled and a second indicator indicating that the automatic brake hold function is enabled. The traveling control unit exclusively executes the automatic brake hold function and the one-pedal function. The output control unit executes at least one of ending display of the second indicator and displaying the first indicator when the one-pedal function is enabled instead of the automatic brake hold function and/or ending display of the first indicator and displaying the second indicator when the automatic brake hold function is enabled instead of the one-pedal function.

Disclosed herein are an apparatus for controlling a vehicle and method thereof. An apparatus for controlling a vehicle, the apparatus includes an inputter configured to receive a start operation signal from a starter, receive an AVH mode operation signal from an Automatic Vehicle Hold(AVH), receive Wheel information, longitudinal acceleration information and AVH switch information from an Electronic Stability Control(ESC), and a determiner configured to determine whether the AVH mode operation signal is an ON operation signal when the start operation signal is an OFF operation signal, and determines whether the at least one of the wheel information, the longitudinal acceleration information and the AVH switch information is in a normal state when the AVH mode operation signal is the ON operation signal and a controller configured to control an Electronic Parking Brake(EPB) to perform parking in the EPB when the at least one of the wheel information, the longitudinal acceleration information, and the AVH switch information is in the normal state.

A method for controlling a force representative of a parking braking of a vehicle, having the steps of: determining, by a data processing unit, a target value of a force representative of a parking braking of the vehicle to be applied, by a first brake caliper, on a first brake disc on the basis of a value of the gradient of the road on which the vehicle is located; determining, by the data processing unit, a value of a first force contribution representative of a service braking of the vehicle applied by a first hydraulic actuator on the first brake disc; determining, by the data processing unit, a value of a second force contribution representative of the parking braking of the vehicle to be applied, by a second electromechanical actuator, on the first brake disc on the basis of a target value of a force representative of a parking braking of the vehicle which can be applied by the first brake caliper on the first brake disc, and of the determined value of the first force contribution representative of a service braking of the vehicle; operating, by the data processing unit, the second electromechanical actuator to apply the determined value of the second force contribution representative of the parking braking of the vehicle on the first brake disc.

The invention has a purpose of improving applicability of 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. A determination section 5A1 and a brake control section 5A4 are provided, the determination section 5A1 determining whether an actual state related to the connection and the disconnection of the clutch matches the assumed state in accordance with a relationship between the secondary information and travel state information indicative of a travel state of the vehicle, and the brake control section 5A4 executing the brake control by using the primary information but not the secondary information in the case where the determination section 5A1 determines that the actual state does not match the assumed state.
