摘要： A vehicle includes wheels, brakes, and a controller. The wheels are configured to propel the vehicle. The brakes are configured to generate a braking torque at the wheels. The controller is programed to, in response to (i) a commanded braking torque and (ii) a relative jounce between two of the wheels exceeding a threshold, operate the brakes to increase the braking torque to less than the commanded braking torque. The controller is further programed to, in response to (i) the commanded braking torque and (ii) a droop of at least one of the wheels exceeding a threshold, operate the brakes to increase the braking torque to less than the commanded braking torque.

摘要： A system includes a vehicle having an electrically powered trailer towed thereto. The vehicle has a vehicle powertrain, and the trailer has a trailer powertrain. A controller, in order to propel the vehicle with the trailer towed thereto, operates the vehicle powertrain and the trailer powertrain according to a combined efficiency map based on (i) an efficiency map associated with the vehicle powertrain and (ii) an efficiency map associated with the trailer powertrain.

摘要： Controlling maximum appliable positive and negative torque for a vehicle is provided. Vehicle data indictive of a driver torque request is received. Maximum appliable positive and negative torques for the vehicle are estimated. Responsive to the driver torque request being positive, the driver torque request is limited to the maximum appliable positive torque. Responsive to the driver torque request being negative, the driver torque request is limited to the maximum appliable negative torque.

摘要： A plurality of light sources are mounted in a vehicular passenger cabin. Each light source illuminates a respective illumination zone with a midpoint. Each light source is configured to illuminate at a plurality of brightness levels up to a full brightness. A gaze tracker monitors an occupant cabin to detect a gaze point. A controller responds to an illumination request from the occupant to actuate at least two light sources to illuminate the passenger cabin at the gaze point. The controller uses the gaze point to select a respective brightness level for each light source based on a proximity of the gaze point to respective midpoints of the illumination zones. At least a first one of the actuated light sources with a midpoint closer to the gaze point provides a higher brightness level than a second one of the actuated light sources with a midpoint farther from the gaze point.

摘要： Terrain characteristics of an off-road area are determined based on a map. The terrain characteristics include a terrain type, a terrain grade, and a presence or an absence of an obstacle. Vehicle characteristics are determined including a ground clearance and a breakover angle. Based on a user level, vehicle parameters for the off-road area are determined based on the terrain characteristics, the vehicle characteristics, and the user input. The vehicle parameters include a speed and a transmission gear. The vehicle parameters for the off-road area are output.

摘要： An operation assistance system for a first vehicle that is connected to a second vehicle that propels the connected first and second vehicles includes: a sensor system of the first vehicle that detects a feature in an operating environment of at least one of the first vehicle and the second vehicle; and a controller that is in communication with the sensor system and that prompts a power assist steering system of the first vehicle to execute a steering command based on the sensor system detecting the feature.

摘要： A snow and ice vehicle accumulation determination and removal system for an electrified vehicle uses weight/load estimation methods based on vehicle sensors and user input to determine if the vehicle has accumulated a significant amount of snow/ice that could negatively affect the vehicle range. When a weight variation exists above a predetermined threshold which can be accounted for only as being due to snow and ice, then the invention may (1) warn the driver of reduced range and the reason for it, (2) perform drivetrain and/or cabin heating that may contribute to melting of the snow and ice (e.g., automatically adjusting powertrain performance to generate increase heat, such as running at a higher RPM), and/or (3) instruct the driver to proceed to an environment which can warm the vehicle (such as a facility equipped with a hot water spraying device).

摘要： A vehicle includes a front axle having left and right front wheels and a rear axle having left and right rear wheels. A steering-wheel assembly is used to control at least the front wheels. Left and right driver-actuatable inputs are supported by the steering wheel assembly. A vehicle controller is programmed to, responsive to actuation of the driver-actuatable inputs, place the vehicle in one or more operating modes such as tank turn, trail turn assist, or diagonal driving mode.
