A vehicle system including a propulsion system coupled to a drive wheel and a friction brake configured to apply braking torque to a vehicle wheel is described. Operation thereof includes an instruction set that is executable to monitor vehicle speed, vehicle grade, and an operator braking request, and execute instructions upon achieving a vehicle speed that is less than a threshold speed. The instructions include controlling, via the friction brake, the braking torque to achieve a desired vehicle speed, and determining an operator acceleration request and the vehicle grade. The controller determines a minimum vehicle grade-based operator acceleration request, and releases the friction brake only when the operator acceleration request is greater than the minimum vehicle grade-based operator acceleration request.

A vehicle may include a dual clutch transmission that adjusts a travel speed of the vehicle based on clutch torque, a brake that makes the vehicle slow down to reduce the travel speed of the vehicle, and a controller that sets a target speed of the vehicle and controls the dual clutch transmission and the brake to allow the travel speed of the vehicle to follow the set target speed.

The controller determines whether the vehicle is in a shuttle motion from the operating position of the forward/reverse travel operating member and the actual traveling direction of the vehicle. The controller determines a target braking force when the vehicle is in the shuttle motion. The controller determines at least one of a target displacement of the travel pump and a target displacement of the travel motor based on the target braking force.

An automatic APS map generating method is provided. The automatic APS map generating method includes measuring a state of charge (SOC) of a battery using a SOC sensor and calculating, a maximum torque of a motor based on the battery SOC and a creep torque based on a current vehicle state to set the creep torque as a minimum torque of the motor. An APS map is generated using an APS percentage table obtained and stored by converting torque values capable of being output by the motor into percentages based on a vehicle speed and an accelerator pedal position sensor (APS) percentage.

To minimize a pedal operation of a driver and to provide convenience of driving by flexibly controlling a maximum creep speed during a creep driving in a traffic congestion section, a vehicle includes: a radar configured to obtain speed information of a preceding vehicle and distance information to the preceding vehicle; a sensor configured to acquire behavior information of the vehicle; a controller configured to determine whether or not the vehicle has entered the traffic congestion section based on the behavior information of the vehicle, to determine a safety distance and a surplus distance related to the preceding vehicle, to determine a maximum creep speed and a creep torque based on the surplus distance, and to control operation of at least one of a motor or an engine to transmit the creep torque to a wheel of the vehicle.

A hybrid vehicle and a control method are provided. The method of controlling a hybrid vehicle including a motor, an engine, and an engine clutch disposed between the motor and the engine includes determining whether to enter a first mode in which both the engine and the motor operate without engagement of the engine clutch, based on at least a first condition related to an accelerator pedal and a second condition related to a required torque condition, determining torque of the motor in consideration of at least required torque upon determining entry into the first mode, and determining an operating point of the engine based on engine generation power to be supplied to the motor with power of the engine.

An infinitely variable transmission (IVT) provides a plurality of transmission modes. At least one mode is a serial mode and at least one other mode is a split-path mode. The IVT provides substantially seamless shifting between the plurality of transmission modes.

A controller can be configured to receive an indication of a measured speed of a vehicle, and determine whether a gradient on which the vehicle is located is below a threshold gradient. The controller can also be configured to provide an output signal to cause a brake of the vehicle to be automatically applied to hold the vehicle stationary, based at least in part on: the received indication of the measured speed of the vehicle being below a threshold speed; and the determination that the gradient is below the threshold gradient.

A method of controlling a creep mode of a motor vehicle with a drive train having a drive unit (1), a gear mechanism (2) and a friction clutch (4) arranged between the drive unit (1) and the gear mechanism (2). The creep function, for controlling the creep mode, having a first partial function for controlling the creep mode, in a case of an activated brake pedal (15), and a second partial function for controlling a creep mode, in a case of a non-activated brake pedal (15). The first partial function of the creep function is only activated once the second partial function of the creep function is activated.

The invention relates to a driving assistance device for a motor vehicle comprising: a camera (9) capable of generating a first map of the environment of the motor vehicle (8); a transit time sensor (12) capable of generating a second map of the vehicle environment (8); a driving assistance module comprising: a fusion unit capable of generating a precise map of the frontal environment of the vehicle, the precise map being generated by the fusion unit as a function of the first map and the second map; a movement computation unit capable of generating an acceleration setpoint of the vehicle as a function of the precise map of the vehicle environment.
