Abstract: Method of selecting and stopping a vehicle using vehicle-to-vehicle communication includes selecting and suppressing a local vehicle including vehicle-to-vehicle communication comprising transmitting a vehicle-to-vehicle locating signal from a host vehicle to local vehicles to obtain a location and a direction of movement for local vehicles within a local area, selecting a local vehicle as a selected vehicle to be suppressed, and suppressing the selected vehicle using vehicle-to-vehicle communication from the host vehicle to the selected vehicle. The suppressing of the selected vehicle by the host vehicle includes providing a warning to the operator of the selected vehicle, limiting speed, along with decelerating and halting of the selected vehicle.

Abstract: Method and device for controlling the braking action of at least one wheel brake of a four-wheel-drive motor vehicle having at least one rear axle and one front axle. A first rpm signal representing the speeds of rotation of the front-axle wheels and a second rpm signal representing the speeds of rotation of the rear-axle wheels are detected. The difference between the first and second rpm signals is then determined, and braking action is controlled as a function of the difference that has been determined.

Abstract: A processing circuit has a computing cycle divided into several subcycles of uniform duration. The time base values of the last three nulls of a square wave signal produced from the sinusoidal signal of a wheel speed sensor are stored in a register with three places. At the beginning of a subcycle the difference D of the latest and of the oldest time base values stored in the register is formed and in some cases after limiting is converted to a value 1/D and stored, while the previously stored oldest value is erased. At the start of a new computing cycle the stored value 1/D is further processed as the new wheel speed.

Abstract: Under conditions which indicate all wheels are unstable, all have been in pressure decrease for a long time, and the vehicle reference velocity has been continuously negatively corrected for a long time, recovery are flags set on all wheels. If all recovery flags are set and four wheel drive axle oscillations are present and the reference velocity has not been in negative correction for too long, the gradient of the vehicle reference velocity is limited to a fixed lesser slope. If one or more recovery flags are set, other measures can be taken, including flattening of the vehicle reference velocity through gradual additions to the calculated vehicle acceleration, and giving longer pressure holds and delaying pressure increase. The recovery flag is reset separately on each wheel only when that specific wheel becomes completely stable.
