Patent number: 9393996Abstract: A controller and control method assists a driver with backing up of a vehicle with an attached trailer. The vehicle has a front axle with steerable front wheels controlled by the driver and a rear axle with non-steerable rear wheels. The trailer has a front axle with non-steerable front wheels and a rear axle with steerable rear wheels controlled by a trailer steering controller. The controller receives an operator-controlled vehicle steering angle and a measured hitch angle. The controller determines a trailer steering angle based on the operator-controller vehicle steering angle and the measured hitch angle. The controller continuously controls the trailer (e.g., via a steering angle of the rear wheels) to maintain a trajectory with substantially no lateral slippage.Type: GrantFiled: January 4, 2013Date of Patent: July 19, 2016Assignee: Honda Motor Co., Ltd.Inventors: Ambarish Goswami, Jimmy Chiu

Patent number: 9168951Abstract: A jackknife warning condition controller and control method notifies a driver of a potential jackknife situation while backing up a vehicle with an attached trailer. The vehicle has a front axle with steerable front wheels controlled by the driver and a rear axle with non-steerable rear wheels. The trailer has a front axle with non-steerable front wheels and a rear axle with steerable rear wheels controlled by a trailer steering controller. The jackknife controller receives an operator-controlled vehicle steering angle and a measured hitch angle. The jackknife warning condition controller determines a directional jackknife warning condition and compares the measured hitch angle with the determined directional jackknife warning condition. If the measured hitch angle satisfies the directional jackknife warning condition then a notification is sent to the driver.Type: GrantFiled: August 15, 2013Date of Patent: October 27, 2015Assignee: Honda Motor Co., Ltd.Inventors: Jimmy Chiu, Ambarish Goswami

Patent number: 9120359Abstract: A method for stability control may include receiving vehicle characteristics of a vehicle of a vehicle-trailer system, trailer characteristics of a trailer of the vehicle-trailer system, or steering inputs for the vehicle. The method may include determining a prediction based on yaw rate deviation for the vehicle determined from the vehicle characteristics, trailer characteristics, or steering inputs or hitch rate oscillation of a hitch coupling the vehicle to the trailer determined from the vehicle characteristics, trailer characteristics, or steering inputs, where the prediction may be indicative of a likelihood of instability for the vehicle-trailer system. The method may include generating control actions based on the prediction and hitch rate feedback from the hitch of the vehicle-trailer system or lateral hitch force feedback.Type: GrantFiled: December 9, 2014Date of Patent: September 1, 2015Assignee: Honda Motor Co., Ltd.Inventors: Jimmy Chiu, Ambarish Goswami, James W.
