Abstract: A method optimizes trailer braking gain for a trailer that is towed behind a vehicle. The method receives an operator selected trailer gain. During a braking event, braking data from at least one sensor is received. Based on the received data and the selected trailer gain, an output trailer gain is provided. During the braking event, pressure in a master cylinder of a vehicle and an actual deceleration of the vehicle is monitored. The method determines if the actual deceleration is sufficient for the monitored master cylinder pressure and if not sufficient, the output trailer gain is automatically adjusted to provide an optimized trailer gain to brakes of the trailer until the actual deceleration of the vehicle matches an expected deceleration at the monitored pressure value.

Abstract: In an optimized hydraulic brake system, a pedal travel sensor is used to improve pedal feel. In order to improve pedal feel, a low pressure is detected in the brake booster and the brake hydraulic system is used to increase wheel pressure. This prevents the operator from having to exert an increasing large force on the brake pedal during a deceleration situation.

Abstract: The present invention is directed to monitoring the loss of pressure in one or more tires by detecting the angular speed variations of one or more wheels of the vehicle over a specified wheel revolution period and analyzing the vibration of the speed various. Changes in the frequency are related to pressure loss, which is indicated to the driver, for example, by displaying the tire pressure loss information on a display.

Abstract: A new method for determining an actual steering wheel angle is provided that does not require re-calculation of a steering center upon each ignition of the vehicle. Accordingly, the vehicle dynamic controller may be activated very quickly after ignition, while a less costly relative steering wheel angle sensor may be employed.

Abstract: A method and system is provided for acquiring and analyzing vehicle motion signals to determine vehicle performance. The sampled vehicle motion signals are transferred from the time domain to the frequency domain using online frequency analysis. Once the frequency spectrum for the sampled vehicle motion data is obtained, the main frequencies and associated amplitudes are identified. Depending on the type of test conducted and the vehicle components to be analyzed, the natural frequencies of interest will be known and identified in the frequency spectrum. Online frequency analysis is used for analyzing the pre-defined frequencies in embedded systems with restricted computational resources and storage facilities. A weight filter matrix is used to calculate the frequency spectrum of interest in real time. The matrix is pre-calculated in accordance with a given sampling time, sampling rate, and selected frequencies.

Abstract: The invention relates to a vehicle location display for a navigation system. The vehicle location display operates in either a graphical display mode or a textual display mode. In the graphical display mode the vehicle location display automatically scales the display to display the current location of the vehicle on the street currently being traveled, the previous cross street, the next cross street, and other vehicle information. When traveling on a freeway, the graphical display mode displays the current location of the vehicle on the freeway being traveled, the previous cross street and the next cross street. In the textual display mode the vehicle location display provides the current vehicle location by street or freeway name, city, county, state, latitude and longitude coordinates. In addition, the current compass heading, the previous cross street and the next cross street are provided.
