A computer includes a processor and a memory, and the memory stores instructions executable by the processor to receive sensor data indicating an obstacle, formulate a first control barrier function for a vehicle based on the sensor data, formulate a second control barrier function for a trailer hitched to the vehicle based on the sensor data, determine a control input based on the first and second control barrier functions, and actuate a component of the vehicle according to the control input.

An approach is provided for determining an autonomous vehicle reaction strategy when facing a wrong way driving vehicle. The approach, for example, involves processing mapping data, sensor data, or a combination thereof to develop a map of an area within a threshold distance of an autonomous vehicle in response to a detection of an oncoming vehicle that is driving in a wrong direction towards the autonomous vehicle. The approach also involves using a decision tree of a plurality of candidate strategies for avoiding the oncoming vehicle to select a strategy based on one or more attributes of the map. The approach further involves presenting the selected strategy in a user interface of the autonomous vehicle.

A traction motor of a hybrid electric vehicle drives a primary pump to provide pressurized hydraulic fluid to engage a power flow path of a multi-ratio transmission. To reduce fuel consumption, the motor is maintained at zero speed until a shift lever is moved into a drive position. After a power flow path is established, the motor speed is again reduced to zero until a driver demands torque by pressing an accelerator pedal. While the traction motor is stationary, an auxiliary pump maintains the fluid pressure to keep the transmission power flow path engaged.

A computing device for a vehicle includes a processor and a memory. The processor is programmed to determine that a vehicle destination includes a boat launch and that the vehicle is towing a trailer including a boat. The computing device guides the vehicle at the boat launch to position the trailer to launch the boat.

A vehicle reverse traveling speed limiting apparatus includes a fluid pressure detector, a brake driver, a limiting speed setter, and a reverse traveling speed controller. The fluid pressure detector detects a brake fluid pressure. The brake driver causes a main brake to perform braking based on a set instruction fluid pressure. The limiting speed setter sets a limiting speed upon reverse traveling. The reverse traveling speed controller executes torque and brake controls to allow an actual vehicle speed of a vehicle to be maintained at the limiting speed. When the actual vehicle speed is higher than the limiting speed, the reverse traveling speed controller sets the instruction fluid pressure to allow the actual vehicle speed to be converged to the limiting speed, and executes, even when the brake fluid pressure is higher than the instruction fluid pressure, the brake control to allow the instruction fluid pressure to be maintained.
