摘要： Methods and apparatus to prevent trailer sway are disclosed. An example apparatus to prevent trailer sway of a trailer coupled to a vehicle includes prediction circuitry to predict, based on sensor data from one or more sensors of the vehicle, whether a trailer sway condition associated with the vehicle is likely to occur, and control activation circuitry to, in response to the prediction that the trailer sway is likely to occur, activate at least one vehicle control of the vehicle to prevent the trailer sway condition from occurring, the at least one vehicle control to include applying torque to at least one of one or more trailer wheels of the trailer or one or more vehicle wheels of the vehicle.

摘要： A vehicle control system for reducing turn radius of a vehicle may include electric motors associated with front and rear wheels of the vehicle. The system may further include a plurality of vehicle sensors to receive information including driving surface type, vehicle speed and handwheel position. The system may also include a controller operably coupled to the electric motors and the sensors to control wheel slip during a turn based on the driving surface type, the vehicle speed and the handwheel position.

摘要： Methods and apparatus to control stability of a vehicle and trailer are disclosed. An example apparatus to control stability of a vehicle and trailer includes stability monitoring circuitry to determine, based on sensor data from one or more sensors of the vehicle, whether a vehicle stability condition associated with the vehicle is satisfied, and stability control circuitry to, in response to the vehicle stability condition not being satisfied, adjust a load distribution on front wheels and rear wheels of the vehicle by adjusting a vehicle pitch.

摘要： A vehicle includes wheels, brakes to control speeds of the wheels, and a hydraulic fluid source in fluid communication with the brakes. The vehicle includes a computer storing instructions to determine that speeds of the wheels are zero and actuate the hydraulic fluid source to provide hydraulic fluid to a first set of one or more of the brakes at a first pressure sufficient to maintain the vehicle body at a present position and to provide hydraulic fluid at a volumetric rate to one or more of the brakes not in the first set, and, while providing hydraulic fluid at the volumetric rate to a brake not in the first set, detect second pressures of the brake not in the first set. The instructions include instructions to determine a volume-pressure curve for the brake not in the first set based on the volumetric rate and the second pressures.

摘要： Methods and systems are provided for adjusting regenerative braking in response to normal loads applied to each of a vehicle's wheels coupled to an electric machine. In one example, a regenerative braking torque for a wheel may be adjusted in response to a normal load that is applied to the wheel as wheel load changes during vehicle braking.
