Embodiment Construction

[0029] figure 1 A schematic view of a vehicle (10) with a device for carrying out the method according to the invention is shown. Here, the vehicle (10) comprises an electronic control unit (20) comprising an electronic storage medium (25). Said electronic control unit (20) can advantageously be referred to as a motor controller of the vehicle (10). The acceleration acquisition unit (30) acquires the acceleration of the vehicle and transmits a signal representing the acceleration to the control unit (20). The acceleration acquisition unit ( 30 ) can include, for example, an acceleration sensor or one or more wheel speed sensors.

[0030] The satellite navigation unit ( 40 ) is configured such that it can acquire the position of the vehicle ( 10 ) in space by means of the navigation satellites. Alternatively or additionally, the satellite navigation unit (40) is configured to obtain a relative velocity between one or more navigation satellites and the vehicle (10) based on a...

Abstract

The invention relates to a method and an apparatus for monitoring a drive of a vehicle in which the practical parameter for representing a movement of the vehicle and a rated parameter for representing the desired movement of the vehicle are compared, wherein the practical parameter for respresting the movement of the vehicle is formed by using signals of radio location.

Description

Background technique [0001] It is known to monitor the vehicle at undesired accelerations by carrying out continuous torque monitoring. In this case, the driver's desired torque is processed, which is determined via the position of the accelerator pedal. Based on the driver's desire and any additional torque requirements that may exist, the setpoint drive torque is calculated. The safety function models the calculation of the nominal drive torque and compares the result of this modeling with the reconstructed actual drive torque. If the comparison results in deviations outside tolerable limits, then a fault is concluded in the drive system of the vehicle and corresponding measures are initiated. For example, fuel injection is interrupted above a certain rotational speed threshold. [0002] Another possibility for monitoring the drive of the vehicle provides acceleration monitoring of the vehicle. Acceleration monitoring can be based on vehicle speed and vehicle acceleratio...
