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.

A system including a supply valve disposed between a chamber and a pressure source, a discharge valve disposed between the chamber and an external atmosphere, a first control unit, and a second control unit. The first control unit coupled with the supply valve by a first switch and with the discharge valve by a second switch. The first control unit outputting signals to the first and second switches to control the supply and discharge valves. The second control unit coupled with the discharge valve by a third switch and a fourth switch, the second control unit outputting signals to the third and fourth switches to control the supply and discharge valves. The first control unit may include a first microcontroller to control the signals of the first control unit using an artificial intelligence (AI) neural network having artificial neurons arranged in layers and connected with each other by connections.

A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

A vehicle control device 1 has a prediction unit 122 that predicts a stopping position of a vehicle T, a gradient identification unit 123 that identifies the amount of gradient in the road surface at the stopping position predicted by the prediction unit 122, a weight identification unit 124 that identifies the weight of the vehicle T, and a braking control unit 125 that brakes the vehicle T by changing the pressure of the brakes of the vehicle T at a changing velocity determined on the basis of the amount of gradient identified by the gradient identification unit 123 and the weight of the vehicle T.

A braking system for a motor vehicle has a first and a second parking brake A first and a second control device each have a driver for driving at least the first and/or the second parking brake actuator. The first control device has a first arbitration unit to data whether a parking brake action should be carried out. The second control device has a second arbitration unit to receive parking brake request data and to ascertain from the received data whether a parking brake action should be carried out. The result of the second arbitration unit is fed to the first arbitration unit as parking brake request data and the result of the first arbitration unit is transmitted to the driver of the first and/or second control device for driving the first and second parking brake actuators.

A method of automatically controlling vehicle auto-hold includes: collecting information on a vehicle traveling condition that applies when a driver operates a brake pedal while a vehicle is traveling; selecting learning data for learning on a pattern of a driver's operation from among pieces of the information collected in the collecting of the information on the vehicle traveling condition and storing the selected learning data; performing the learning on the pattern of the driver's operation based on the learning data and generating a categorization model for the pattern of the driver's operation according to a result of the learning; and determining whether or not to cause the auto-hold switch to enter an automatic operation mode while the vehicle is traveling, using the categorization model, and selectively causing the auto-hold switch to enter the automatic operation mode according to a result of the determining.

Method for holding a vehicle in the stationary state, which has the following steps: (a) if the vehicle has an automatic transmission, engaging a parking lock, or if the vehicle has a manual transmission, engaging a gear, (b) at least temporarily, automatically carrying out vehicle movement monitoring by means of a sensing device; and (c) automatically activating a brake device of the vehicle in order to apply a braking force if the sensing device signals a vehicle movement.

Provided is an electronic parking brake (EPB) system including an actuator of an EPB operated by a motor, the EPB system including: a motor driving unit configured to drive the motor; and a controller electrically connected to the motor driving unit, wherein the controller is configured to: in response to a parking switch being in an activated state, determine whether an engine is in an off state; upon determining that the engine is in the off state and operation information of the EPB is parking apply information corresponding to a parking apply mode (Apply), determine whether a rolling of the vehicle occurs based on a wheel pulse; upon determining that the rolling of the vehicle occurs, determine whether the rolling corresponds to a driver's steering intention based on external collision information and a steering angle; and upon determining that the rolling corresponds to the driver's steering intention, control the motor driving unit not to re-clamp the EPB.

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.

A parking brake apparatus is provided for a vehicle having components of a parking brake system. The parking brake apparatus comprises a parking brake controller arranged to (i) obtain a first signal indicative of whether a hill start assist system is installed on the vehicle, and (ii) provide one or more control signals to be applied to components of the parking brake system to apply parking brakes when the first signal is indicative of a hill start assist system installed on the vehicle is present and a second signal indicative of the hill start assist system being activated is received.
