A backup control unit for controlling motion of a heavy-duty vehicle during a minimum risk maneuver, where the backup control unit is arranged to receive data indicative of a planned sequence of vehicle control commands from a main vehicle control unit. The backup control unit comprises a first vehicle model configured to map the planned sequence of vehicle control commands into a desired vehicle behavior and is arranged to obtain a measured vehicle behavior from one or more vehicle sensors. Also, the back-up control unit is arranged to determine an adjusted sequence of vehicle control commands based on the planned sequence of vehicle control commands and on a deviation between the desired vehicle behavior and the measured vehicle behavior, and to transmit the adjusted sequence of vehicle control commands to a motion support device, MSD, control unit of the vehicle.

An automatic torque control system and methods for automatically controlling a torque of a vehicle are disclosed. The method includes detecting when the vehicle engages a load. The method further includes automatically decreasing the torque when the vehicle engages the load and prior to one or more wheels of the vehicle slipping.

The disclosure is generally directed to an advanced driver assistance system (ADAS) enhancement system. In an example method of operation, a processor of the ADAS enhancement system obtains information about a laden weight of a vehicle, identifies a setting associated with an operation of an ADAS of the vehicle (a braking operation, a cruising speed control operation, a lane maintaining operation, etc.) and modifies the first setting based on the laden weight of the vehicle. For example, the ADAS enhancement system may increase a first braking distance set by the ADAS to a second braking distance system based on the laden weight of the vehicle. As another example, the ADAS enhancement system may change a first level of responsiveness to an action performed by the driver of the vehicle to a second level of responsiveness in proportion to the weight of a cargo item in the vehicle.

A vehicle includes one or more transceivers configured to communicate with a server; and a controller programmed to responsive to detecting an extra load to the vehicle, obtain a first candidate energy consumption rate corresponding to the extra load from the server, calculate an estimated energy consumption rate using the first candidate energy consumption rate, and calculate a distance to empty using the estimated energy consumption rate.

Methods and systems for improving fuel economy and reducing emissions of a vehicle with an electric motor, an engine, an energy storage device, and a controller are disclosed. The method includes obtaining current state information including a current hybrid control surface, and determining a target hybrid control surface for the vehicle based on the current state information.

A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

A method in a control arrangement of a vehicle and a control arrangement for a vehicle for downshifting gears in an uphill slope are presented. The method comprises, when the vehicle is travelling in an uphill slope using an initial gear of the vehicle's automated manual transmission gearbox: simulating at least one speed profile for a downshift to, and a usage of, at least one gear; determining that a minimal speed of each one of the at least one simulated speed profile has a value indicating that the actual speed of the vehicle will be less than or equal to zero in the uphill slope; opening a clutch before is reduced to a value less than zero; activating at least one vehicle brake; shifting vehicle's automated manual transmission gearbox to a start gear; closing the clutch; and deactivating the at least one vehicle brake.

An apparatus for controlling a change in speed of a vehicle, includes: an auxiliary braking signal unit receiving an auxiliary braking related signal from a driver; a vehicle control unit receiving the auxiliary braking related signal from the auxiliary braking signal unit while controlling the vehicle; a motor control unit receiving a command for auxiliary braking from the vehicle control unit and decelerating the vehicle by regenerative braking of a driving motor; a transmission control unit controlling a transmission during deceleration of the vehicle and transmitting information of whether a change in speed is performed to the vehicle control unit; and a braking control unit connected to a brake through a fluid pressure line, and controlling the brake so that the brake applies braking pressure to a wheel by an amount of reduction in regenerative braking torque when the transmission is downshifted.

A steering control device 10 is equipped with: a first specification unit 121 for specifying an expected travel position where a vehicle is expected to travel in the traffic lane in which the vehicle is travelling; a second specification unit 122 for specifying information about the weight of the vehicle; an adjustment unit 123 for adjusting the expected travel position in the vehicle-widthwise direction on the basis of the expected travel position of the vehicle and the weight information; and a steering control unit 124 for controlling steering on the basis of the adjusted expected travel position.

An information-processing device includes a first controller configured to determine the number of users using a vehicle that enters or leaves a parking lot or a weight of the vehicle and a second controller configured to determine a position where the vehicle is stopped within a predetermined area of the parking lot on the basis of the number of users or the weight determined by the first controller.
