Patent number: 9592800Abstract: Various embodiments of a towing vehicle controller and methods for brake control of a towed vehicle are provided. A towing vehicle controller includes an input for receiving a load signal indicative of a load of a towed and towing vehicle combination; an input for receiving a stability signal indicative of at least one of a yaw rate, a steering angle, and a lateral acceleration of the towing vehicle; and an input for receiving a deceleration signal indicative of an automated deceleration request. Control logic is capable of determining a comparison value prior to receiving the deceleration signal and after receiving the load signal and the stability signal, wherein the determination of the comparison value is based on the load signal and the stability signal. After the deceleration signal is received, the control logic determines a brake control transmission signal based on the deceleration signal and the comparison value.Type: GrantFiled: April 9, 2015Date of Patent: March 14, 2017Assignee: Bendix Commercial Vehicle Systems LLCInventors: Eric A Matoy, Michael D Tober

Patent number: 9573591Abstract: A method of controlling drivability of a vehicle detects an overall load acting on the vehicle. A mass of the vehicle or an estimate thereof is obtained. A controller determines whether the vehicle is negotiating a curve during a driving situation. If the vehicle is negotiating a curve during the driving situation, the controller determines whether the vehicle has a tendency to oversteer or to understeer. The load acting on the vehicle is dynamically changed or a suspension stiffness of the vehicle is dynamically adjusted to reduce the tendency of the vehicle to oversteer or to understeer.Type: GrantFiled: March 18, 2015Date of Patent: February 21, 2017Assignee: Continental Automotive Systems, Inc.Inventors: Eric A. Matoy, Richard N. Blust, Justin A. Ruediger, Chris A. Harrison

Patent number: 9311761Abstract: A method identifies, for a vehicle, a low friction surface from a road surface with a slope. With the vehicle at standstill, the vehicle ignition is switched on. A normal load for the vehicle is calculated. It is determined if the vehicle is moving, and if the vehicle is moving, a vehicle load is calculated using suspension information from the vehicle. A road slope angle is calculated based on the calculated vehicle load and calculated normal load. A normal slope angle is calculated and is compared to the calculated road slope angle to determine if the vehicle is on a low friction surface or on a sloped surface. In accordance with another aspect of an embodiment, a method determines whether a trailer is coupled to a vehicle.Type: GrantFiled: November 21, 2014Date of Patent: April 12, 2016Assignee: Continental Automotive Systems, Inc.Inventors: Bo Ye, Michael G. Schneider, Joshua Frankfurth, Eric A. Matoy
