In a vehicle control system, a standard driving model of a vehicle is stored in a model storage unit. A risk level determination unit compares a driving operation by a driver with a normative driving operation output from the standard driving model and determines a risk level of the driving operation. An operation limiting unit inputs, to a drive unit, a drive signal adjusted based on the determination by the risk level determination unit on the risk level of the driving operation by the driver so as to limit driving of the drive unit.

An electric vehicle includes a vehicle controller. The vehicle controller is capable of switching a traveling mode of the electric vehicle between a first traveling mode and a second traveling mode that applies driving-force maps for enhancing a rough-road capability from a rough-road capability in the first traveling mode. The vehicle controller is capable of switching the traveling mode to the second traveling mode in forward traveling and in backward traveling and is configured to apply, to the backward traveling in the second traveling mode, a first driving-force map of the driving-force maps, the first driving-force map having gentler characteristics than a second driving-force map of the driving-force map applied to the forward traveling in the second traveling mode.

An imaging system and method of a trailer backup assist system is provided and includes a camera having an image sensor. The camera is mounted on the rear of a vehicle and images a target provided on a trailer. A controller is included for adjusting an image capture setting of the camera based on a status input from a vehicle lighting system, image data from the camera, and locational input from a positioning device.

A stop/start hybrid vehicle includes an engine configured for stopping and restarting during travel, a multiple-ratio transmission, a brake pedal, and an electronic parking brake. The transmission can be shifted into reverse gear either when the brake pedal is applied or unapplied. At least one controller is programmed to control the vehicle under these scenarios. If the engine is off and the brake pedal is applied when the transmission is shifted into reverse, the controller restarts the engine. If the engine is off and the brake pedal is unapplied when the transmission is shifted into reverse, the controller inhibits the engine from restarting until the brake pedal is applied. The controller can also be programmed to apply the electronic parking brake while the brake pedal remains unapplied after a predetermined time from the transmission being shifted into the reverse gear.

A trailer backup steering input apparatus is coupled to a vehicle. The trailer backup steering input apparatus comprises a rotatable control element (e.g., a knob) and a rotatable control element movement sensing device. The rotatable control element biased to an at-rest position between opposing rotational ranges of motion. The rotatable control element movement sensing device is coupled to the rotatable control element for sensing movement of the rotatable control element. The rotatable control element movement sensing device outputs a signal generated as a function of an amount of rotation of the rotatable control element with respect to the at-rest position, a rate movement of the rotatable control element, and/or a direction of movement of the rotatable control element with respect to the at-rest position.

According to one embodiment, in response to a request for a three-point turn, a set of forward turning paths is generated based on a maximum forward turning angle associated with an ADV. A set of backward tuning paths is generated based on a maximum backward turning angle associated with the ADV. A set of three-point turn path candidates is generated based on the forward turning paths and the backward turning paths. For each of the three-point turn path candidates, a path cost is calculated using a predetermined cost function. One of the three-point turn path candidates with the lowest path cost is selected as the final three-point turn path to drive the ADV to make a three-point turn.

A drivetrain system includes a controller that is programmed to, in a presence of a request for increased drivetrain torque that results in reversal of drivetrain torque direction, command an increase in drivetrain torque at a reduced rate while a value that is based on drivetrain speed difference remains within a predetermined range absent a braking torque request exceeding a threshold. The controller is further programmed to command the increase at an accelerated rate upon the braking torque request exceeding the threshold.

An apparatus includes a position circuit structured to monitor a position of an accelerator of a vehicle and a speed circuit structured to monitor a speed of the vehicle. The position corresponds with an associated response of a prime mover of the vehicle. The associated response includes at least one of a torque output and a power output of the prime mover. The apparatus further includes a response management circuit structured to receive an indication regarding the position of the accelerator and the speed of the vehicle; determine that the indication satisfies a remapping condition, the remapping condition including at least one of a creep condition, an obstacle condition, a deceleration condition, and a reverse condition; and dynamically remap the associated response of the prime mover of the vehicle based on the position of the accelerator in response to the indication satisfying the remapping condition.

A vehicular backup assist system includes an upper sensor disposed at a rear upper portion of a vehicle and sensing rearward of the vehicle at a height relative to ground of the rear upper portion of the vehicle, and a lower sensor disposed at a rear lower portion of the vehicle and sensing rearward of the vehicle at a height of the rear lower portion of the vehicle. The system, during a reversing maneuver of the vehicle, and via processing at an electronic control unit of sensor data captured by the upper and lower sensors, detects presence of objects rearward of the vehicle. During the reversing maneuver, the system, via processing of sensor data captured by the upper sensor, detects presence of an object at the height of the rear upper portion of the vehicle and alerts a driver of the vehicle of the detection of the object.

A vehicle hitching assistance system including a controller determining a trailer target area to a rear of the vehicle. The trailer target area is positioned within left and right lateral vehicle steering limits, defined in a lateral direction between left and right boundaries respectively spaced inwardly of the left and right lateral vehicle steering limits by one of a system perception factor or a vehicle geometry factor, and defined in a longitudinal direction between a minimum movement limit and a maximum perception limit. The controller further identifies a trailer coupler within the trailer target area and outputs a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler during movement of the vehicle.
