Abstract: A method of controlling a trailer brake system using a trailer brake controller positioned within a passenger vehicle is provided. The method includes obtaining intended braking inputs and developing an effective baseline trailer brake controller output profile based thereon. The method scales the effective baseline trailer brake controller output profile in response to an adjustable gain setting set by an operator. A vehicle velocity is obtained and used to calculate a correction factor to the effective baseline trailer brake controller output profile. The effective baseline trailer brake controller output profile is then adjusted using the correction factor to generate a corrected trailer brake controller output signal.

Abstract: A control system for controlling a safety system of an automotive vehicle having a transmission and a differential. The system includes left and right wheel speed sensors associated with respective vehicle wheels and generating left and right wheel speed signals, and a transmission output shaft speed sensor generating a transmission output shaft speed signal. A controller is coupled to the wheel speed sensors and the transmission output speed sensor, and determines a reference wheel speed for one of the left or right wheels as a function of the other of the left or right wheel speed signal and the transmission output shaft speed signal. The controller controls the safety system in response to the determined reference wheel speed.

Abstract: A method of marketing includes encouraging existing customers to send messages to persons known to them endorsing products they have used and encouraging the other persons to use the products. In particular, the customer's database of contacts is used to generate the message.

Abstract: A method for determining a center position of a vehicle steering system, said method comprising the steps of reading a plurality of predetermined inputs. The method includes the steps of roughly estimating a center position of the vehicle steering system after the vehicle begins moving based upon the read predetermined inputs and determining whether the steering wheel of the vehicle steering system is approximately straight. The method further includes the steps of accurately estimating a center position of the vehicle steering system if the steering wheel of the vehicle steering system is approximately straight and concluding that the accurately estimated center position is the center position of the vehicle steering system if the steering wheel of the vehicle steering system is approximately straight and Concluding that the roughly estimated center position is the center position of the vehicle steering system if the steering wheel of the vehicle steering system is not approximately straight.
