Problems solved by technology

Additionally, wheel diameters come with static and dynamic tolerances
Therefore, when the torque of the engine reference system is converted into a force in the vehicle reference system, the tolerance of the force and thus the acceleration calculated therefrom is also increased.

Embodiment Construction

[0021] exist figure 1 A schematic diagram of a vehicle 10 with a device for carrying out the method according to the invention is shown in . Vehicle 10 here has at least one engine 20 , 30 , for example an internal combustion engine 20 and / or an electric motor 30 . The at least one engine 20 , 30 is controlled by an engine control unit 40 . The engine control device 40 includes an electronic storage medium 45 . In an advantageous refinement of the invention, the at least one motor 20 , 30 includes means for determining the rotational speed of the at least one motor 20 , 30 .

[0022] The vehicle also has a unit for providing a change in vehicle potential energy 50 . The unit for providing potential energy change 50 can include a sensor, in particular a gyroscope, which detects the inclination angle of vehicle 10 . Alternatively, the unit for providing the change in potential energy 50 can also comprise a pressure sensor and thus provide the change in potential energy of th...

Abstract

A method is provided for monitoring a drive of a vehicle, a change in an internal energy of the vehicle being compared with a power of the vehicle to be expected.

Description

technical field [0001] The invention relates to a method for monitoring a vehicle drive. Background technique [0002] It is known to monitor the vehicle for undesired accelerations by carrying out continuous torque monitoring. The driver's desired torque determined via the accelerator pedal position is processed here. The setpoint drive torque is calculated as a function of the driver's wishes and possibly existing additional torque requirements by driver assistance systems and / or auxiliary devices. The safeguard function simulates the calculation of the nominal drive torque and compares the simulated result with the nominal drive torque. If the comparison results in a deviation outside the permissible range, a fault is concluded in the drive system of the vehicle and corresponding measures are initiated. For example, fuel injection can be prevented above a certain rotational speed threshold. [0003] Another possibility provides acceleration monitoring of the vehicle. ...
