A control system for an electric motor comprises a controller which receives as an input a demanded motor current and produces at an output an intermediate voltage demand signal, a voltage demand signal correction means arranged to generate a voltage demand correction signal, and a combining means arranged to combine the intermediate voltage demand signal and the voltage demand correction signal to produce an actual voltage demand signal that is applied to the motor by pulse width modulation of the switches of a motor bridge driver. The correction signal compensates for unwanted non-linearities caused by interlock delays in the switching of the motor bridge switches.

Motor control system

A stabilizer () for the anti-roll stabilization of a vehicle (). The stabilizer () has a first stabilizer element () and a second stabilizer element (). The first stabilizer element () is, or can be, coupled to a first wheel suspension element () of the vehicle () and the second stabilizer element () is, or can be, coupled to a second wheel suspension element () of the vehicle (). Furthermore, the stabilizer () is provided with an electric motor () designed to rotate the first stabilizer element (), relative to the second stabilizer element () in response to a control signal, so as to decouple the first wheel suspension element () from the second wheel suspension element (). In this case the control signal represents a signal determined on the basis of a field-orientated control system.

Anti-roll bar for the rolling stabilization of a vehicle and method for operating such an anti-roll bar

A motor vehicle control system for controlling a motor vehicle with a hybrid drive comprising an internal combustion engine and an electric motor, with a strategy sub-component, a control sub-component and an actuator sub-component. The functional components include at least an internal combustion engine functional component, a transmission functional component, such that the strategy sub-component () of the hybrid functional component () comprises an operating status prescription module which determines a prescribed value for the operating status of the hybrid drive and transmits the prescribed value to the control sub-component () of the hybrid functional component () such that the control sub-component () of the hybrid functional component () comprises a first module () and a second module ().

Hybrid drive motor vehicle control system comprising distributed functional components for controlling hybrid drive operating status

A control system for controlling a vehicle with a hybrid drive comprising an internal combustion engine and an electric motor and a plurality of functional components each divided into strategy, control and actuator sub-components. The functional components include engine, transmission and hybrid functional components. The strategy sub-component of the hybrid functional component comprises an operating status prescription module which determines a recommended value for the operating status of the hybrid drive and transmits the recommended value to the control sub-component. The possible recommended value that can be determined by the operating status prescription module is a preselected hybrid driving condition, and if the operating status prescription module of the strategy sub-component transmits the preselected hybrid driving condition, as the recommended value, to the control sub-component, then the strategy sub-component prescribes a change from electric to hybrid driving, while the control sub-component determines when change occurs.

A process of operating a motor vehicle drive train that comprises at least one hybrid drive having a combustion engine and an electric motor with a clutch connected between the combustion engine and the electric motor, and an automatic transmission is arranged between the hybrid drive and an output. The process including the step of disengaging the clutch to carry out a shift, after a reduction of load at the internal combustion engine and after a reduction of the torque that is transmitted between the internal combustion engine and the electric motor. Subsequently carrying out a gear shift by the automatic transmission and, thereafter, increasing the torque that is transmitted by the clutch. Increasing the load from the combustion engine, and optionally engaging the clutch. A load transfer by the electric motor occurs before and/or after the gear shift in the transmission is carried out.

Method for operating a drive train

A method of operating a drivetrain of a motor vehicle. The drivetrain comprises a drive aggregate formed as a hybrid drive with a combustion engine and an electric machine, and a transmission connected between the drive aggregate and a drive output. The drivetrain also comprises a pressure reservoir system with at least one pressure reservoir and at least one pressure generator by the combustion engine in order to fill the pressure reservoir. A pressure in the pressure reservoir of the pressure reservoir system is measured and a value of the actual pressure, in the pressure reservoir system, is compared with at least one threshold value. When the actual pressure value is higher than a threshold value, stopping of the combustion engine is permitted, whereas if the actual pressure value is lower than the threshold value, stopping of the combustion engine is not permitted.
