Abstract: The present invention relates to a method and a device for adjusting the output torque or the output speed of an internal combustion engine in order to protect the differentials. The crux and advantage of the present invention lies in calculating and monitoring the rpm differences or the rpm differences in the transverse direction of any vehicle (front-wheel-, rear-wheel-, and four-wheel-drive) as well as the difference in the Cardan speeds that exists in the longitudinal direction in four-wheel drive vehicles. When a specifiable limiting value is exceeded, an automatic reduction in the drive torque or an automatic limiting of the engine speed to a manageable level takes place. This protective function for the differentials cannot be switched off and is available even in the passively activated drive-torque AMR control system. It can only be realized by software using already existing sensors and actuator devices. The application outlay is minimal.

Abstract: In a lean burn engine for a vehicle wherein an ordinary air-fuel ratio and a lean air-fuel ratio are selectively applied, an engine output is reduced when a slip of a drive wheel is detected. By controlling the air-fuel ratio when the engine output is reduced to an ordinary air-fuel ratio, the engine is prevented from becoming unstable even when output is reduced at a lean air -fuel ratio. Preferably, when the engine output reduction has terminated, the air-fuel ratio is returned to the air-fuel ratio prior to the output reduction.

Abstract: In a driving force control system for a vehicle, an angular velocity of the course direction of the vehicle body is calculated. On the other hand, a target angular velocity of the course direction is determined based on a steering angle and a vehicle speed. Then, based on the degree of the deviation of the calculated angular velocity from the target angular velocity, a correction coefficient for reducing an engine power is generated. When the vehicle traces off the course in the marginal condition on the low friction coefficient road, the correction coefficient reduces the engine power to prevent the vehicle from going out of the course.

Abstract: A method for reducing the brake pressure commanded by a traction control system of a machine is disclosed. The method includes the steps of estimating the instantaneous heat energy associated with an applied brake, estimating the accumulated heat energy associated with the applied brake during the time period that the brake is applied in response to the instantaneous heat energy; comparing the accumulated heat energy to a maximum allowable heat energy value; and reducing the magnitude of the braking command signal to reduce the applied brake pressure in response to the accumulated heat energy being greater than the maximum allowable heat energy value.

Abstract: A motor vehicle brake control system having traction control and incorporating controller features and methods of operation which interrupt activation of the traction control system in conditions likely to develop excessive brake temperatures, exceed available brake pressure limitations, or other adverse brake conditions. This feature is provided by monitoring the behavior of the system, and based on known braking system characteristics, disabling the traction control when certain parameters are exceeded. The system provides these features without the need to directly measure brake temperature, brake system pressure or other physical parameters.

Abstract: A method ensures that, even under wet conditions, the unrestricted intended braking effect is always achieved on wheels of a vehicle brake system. At the same time, the service life of the brake system is not to be influenced appreciably. When a sensor device detects that wet conditions influencing the braking effect are present and it has been detected that the braking effect of a brake could be impaired, a temporary braking operation is carried out on at least that particular brake, in such a way that the deceleration of the vehicle cannot be perceived by the driver.
