| 20100125399 | ADAPTIVE CRUISE CONTROL BRAKING WITH DECELERATION MONITORING - In one embodiment, a vehicle speed control device includes an electronic control unit (ECU). A forward vehicle sensor, electrically communicating with the ECU, generates a forward vehicle signal as a function of whether a forward vehicle is detected. The forward vehicle signal indicates a speed and a distance to the forward vehicle. A speed sensor, electrically communicating with the ECU, senses a driven vehicle speed. Control logic, electrically communicating with the ECU and the forward vehicle sensor, controls the driven vehicle speed as a function of a driven vehicle acceleration and the forward vehicle signal. The control logic sets a fault status as a function of the driven vehicle acceleration and the forward vehicle signal. | 05-20-2010 |
| 20100106388 | HEAVY VEHICLE TRAILER ABS MODULE - A heavy vehicle trailer antilock braking system module includes a module control port receiving a pressure signal, a module exhaust port fluidly communicating with atmosphere, a first switching valve, a second switching valve, a relay valve, and control logic. The first switching valve includes an input port and an output port. The first switching valve input port fluidly communicates with the module control port. The second switching valve includes an input port and an output port. The second switching valve output port fluidly communicates with the module exhaust port. A relay valve includes a supply port, a delivery port, an exhaust port, and a control port. The relay valve control port fluidly communicates with the first switching valve output port and the second switching valve input port. The delivery port fluidly communicates with the supply port and the exhaust port as a function of a pressure signal at the relay valve control port. Control logic causes the second switching valve input port to fluidly communicate with the second switching valve output port for a predetermined time after electrical power is no longer supplied to a vehicle service brake stop lamp. | 04-29-2010 |
| 20100106385 | SPRING BRAKE VALVE - Methods and valve arrangements for controlling the flow of pressurized air from a tractor to a trailer reservoir and to a trailer spring brake chamber. In one exemplary embodiment, pressurized air from a tractor is supplied from a tractor to the trailer reservoir and to the trailer spring brake in different filling modes based on a user input. In another exemplary embodiment, pressurized service air is used to charge or partially charge the trailer reservoir. | 04-29-2010 |
