The present disclosure provides a method of controlling driving of a vehicle by estimating a road frictional coefficient, the method including distributing torque to a front wheel and a rear wheel to satisfy required torque for driving, by a controller, in a four-wheel drive (4WD) vehicle including a front wheel driving device and a rear wheel driving device installed therein, and performing torque excitation control for increasing torque applied to one of the front wheel and the rear wheel to which the torque is distributed while the vehicle is driven, and simultaneously, changing torque applied to a remaining one of the front wheel and the rear wheel in such a way that the sum of front wheel torque and rear wheel torque satisfies required torque, by the controller.

A user interface in a vehicle system includes a processor programmed to output a user interface screen that includes a list of one or more selectable items found in a plurality of pages associated with the user interface screen, wherein the user interface screen includes a header section including information located along a top portion of the user interface screen, and in response to a scrolling action initiated by a user and a vehicle speed above a vehicle speed threshold, hide the header section.

A control method of an in-wheel motor vehicle includes: determining, by a controller, a state of a steering load that is a load of a steering system; maintaining, by the controller, a front wheel brake in a released state, when the state of the steering load is in a high load state of a predetermined level or more; determining, by the controller, a tire angle of a front wheel according to a driver steering input based on driver steering input information in the released state of the front wheel brake; determining, by the controller, a required tire rotational angle of the front wheel by using the determined tire angle of the front wheel; and reducing, by the controller, the steering load by driving an in-wheel motor of the front wheel for a compensation by the determined required tire rotational angle of the front wheel.

A vehicle operating method comprising generating a base torque reserve for an engine based on a position of an accelerator pedal and a position rate of change of the accelerator pedal, where the base torque reserve is an air reserve of the engine generated by the engine. The base torque reserve may further be generated based on one or more of a drive mode, a vehicle altitude, a battery state of charge (SOC), and a transmission gear, in at least one example.

Described herein is a method for reducing noise in a driveline of a motor vehicle, the method including detecting a condition initiating a noise event of the driveline by using one or more sensors on board the vehicle; and controlling, as a function of the detected condition and of a signal of said one or more sensors, an actuation of one or more actuators that govern corresponding devices that can be connected to the driveline and configured for generating a torsional pre-load condition in the driveline itself.

A vehicle includes an actuator, a drivetrain configured to receive mechanical power from the actuator, an accelerator pedal position sensor configured to output a driver-demanded torque, and a controller in electric communication with the sensor and the actuator. The controller is programmed to receive the driver-demanded torque and output a shaped torque command to mitigate driveline disturbances caused by backlash and shaft compliance.

A method for controlling a starting process of a vehicle includes activating a control sequence and setting a control sequence signal, defining a maximum engine drive torque, and detecting a drive request for a starting process. The method further includes, in response to the drive request, controlling a clutch-gearbox unit with an engagement process duration, controlling wheel slip of driven wheels by determining wheel speeds of the driven wheels and at least setting an output drive torque at the output shaft, and redefining the maximum engine drive torque depending on the wheel slip and a driving speed. The method also includes deactivating the control sequence and resetting the control sequence signal when limit values are reached.

An electronic controller (10) for a motor vehicle (100), the controller being configured to determine when at least one wheel (111, 112, 114, 115) has lost traction, wherein when the controller (10) determines that at least one wheel (111, 112, 114, 115) has lost traction the controller (10) is configured to provide an output to a driver indicative of the at least one wheel (111, 112, 114, 115) that has lost traction.

Disclosed is a method for control a vehicle with a drive system comprising an output shaft of a combustion engine and a planetary gear with a first and a second electrical machine, connected via their rotors to the components of the planetary gear, the vehicle is started by controlling the first electrical machine to achieve a torque thereof, so that the requested torque is transmitted to the planetary gear's output shaft, and controlling the second electrical machine to achieve a torque, so that the desired power to electrical auxiliary aggregates and/or loads in the vehicle, and/or electric energy storage means, if present in the vehicle, for exchange of electric energy with the first and second electrical machine is achieved.

Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration or deceleration, and speed. In some aspects, a lead vehicle can wirelessly transmit information from various electronic control units (ECUs) to ECUs in a rear vehicle. A rear vehicle can then apply transformations to the information to account for a desired following distance and a time offset. ECUs onboard the rear vehicle may then be controlled based on the ECUs of the lead vehicle, the desired following distance, and the time offset.
