A vehicle includes a powertrain having a powerplant and a transmission. The transmission has an input shaft operably coupled to the powerplant and an output shaft operably coupled to driven wheels. A vehicle controller is programmed to, in response to a brake pedal being applied, a speed of the output shaft being less than a threshold speed, and a position of an accelerator pedal being less than a threshold position, automatically engage friction brakes regardless of road grade and continue engagement of the friction brakes despite subsequent release of the brake pedal such that the friction brakes are engaged to hold the vehicle stationary independent of the road grade. The controller is further programmed to release the friction brakes in response to a position of the accelerator pedal being greater than a second threshold position.

This vehicle control device comprises: a slope movement start assistance unit that maintains a braking force until elapse of a predetermined period since execution of a braking release operation for releasing a braking force applied to the wheels of a vehicle equipped with a motor serving as a power source such that the vehicle does not go down a slope; an acquisition unit that acquires each of the gradient of a road surface on which the vehicle is stopped and the total weight of the vehicle; and a control unit that executes control for causing the motor to generate, in the predetermined period, a threshold torque that corresponds to each of the gradient of the road surface on which the vehicle is stopped and the total weight of the vehicle.

Braking system includes a brake, first valve that actuates the brake based on user input, second valve configured to selectively actuate the brake, and valve actuation system including a user input device moveable between first and second positions. A brake sensor provides a signal indicative of actuation of the first valve. The valve actuation system activates the second valve if the user input device is in the first position and the first valve engaged, retaining the second valve in active state if the first valve is disengaged, deactivating the second valve if the user input device is in the second position.

A method of controlling an electronic parking brake of a vehicle having a dual clutch transmission. The method includes: identifying a slope of an area in which the vehicle is located in order to determine whether the identified slope exceeds a predetermined slope value; determining whether both of two clutches are opened in a safe mode when the identified slope exceeds the predetermined slope value; determining whether the vehicle moves upward in a front direction when both of the two clutches are opened; and operating the electronic parking brake when the vehicle moves upward in the front direction. When the vehicle moves upward in the front direction on the inclined road, the electronic parking brake is automatically operated to prevent the vehicle from slipping in the rear direction. Therefore, the method can effectively improve the safety of the driver and vehicle even when the driver is inept in pedal operation.

A hill start assist system for a motor vehicle including a control system using sensor data from at least one sensor to provide the hill start assist with improved response behavior. The control system activating the hill start assist automatically and independently of whether the motor vehicle is on an upward incline depending on sensor data from the sensor indicating a local upward gradient in a driving surface in a region of a vehicle axle.

Hill hold control for a vehicle that is executed in response to idling stop of an engine is cancelled on the condition that a command to restart the engine for recovery from the idling stop is issued and an engine rotation speed is higher than or equal to a predetermined determination value; whereas, cancellation of the hill hold control is prohibited when the engine is in process of being stopped through the idling stop.

An electronic parking brake system that generates a clamping force required for parking of trailer-mounted towing vehicles includes an electronic parking brake provided on at least one of front and rear wheels of the towing vehicle; and a controller configured to receive a front wheel speed, a rear wheel speed, and a longitudinal acceleration of the towing vehicle, determine whether or not the trailer is mounted based on changes in the received front wheel speed, rear wheel speed, and longitudinal acceleration when the towing vehicle passes a speed bump, and determine the clamping force required for parking according to whether or not the trailer is mounted when parking is operated, and control the electronic parking brake to generate the determined clamping force.

A computer-implemented method of performing static heating of an electric motor comprises: applying a brake to a wheel of a vehicle that has an electric motor; determining an incline of the vehicle; and in response to the incline being within a first incline range, providing first current to the electric motor for static heating, the first current selected so as to not produce torque in the electric motor.

A method for controlling a braking system of a vehicle for the distribution of braking forces for parking the vehicle involves receiving, by a system for controlling the braking system, a first piece of information representative of a first working temperature of a first vehicle front axle, a second piece of information representative of a second working temperature of a second vehicle rear axle, a third piece of information representative of a gradient of the vehicle, a fourth piece of information representative of a coefficient of friction between the vehicle and a road, and a fifth piece of information representative of a weight of the vehicle, and determining a first target braking force to be applied to the first front axle and a second target braking force to be applied to the second rear axle based on the first, second, third, fourth and fifth pieces of information.

Disclosed is a corner module apparatus for a vehicle. The corner module apparatus includes processors configured to receive a braking initiation manipulation input of a vehicle from a driver. The corner module apparatus also includes a controller configured to perform braking of the vehicle by independently controlling steering of four wheels of the vehicle based on a direction angle when the braking initiation manipulation input is received by the one or more processors in a state in which the vehicle is positioned on the slope. The direction angle is an angle between an inclined direction of a slope and a longitudinal direction of the vehicle.
