Definitions
- the invention relates to a method for reducing the traction slip of vehicle wheels, which are driven by different engines.
- ASR slip controllers
- a slip control is proposed on a first group of wheels, which is driven by a first motor
- the first engine may be an internal combustion engine and the second engine may be an electric motor. In this case, am
- a group of wheels may comprise one or more wheels according to the invention.
- the invention is also applicable to vehicles having a plurality of electric motors, such as e.g. for vehicles with wheel hub motors.
- the road friction coefficient is preferably estimated. This can be one
- the electric motor is preferably controlled so that it generates only a portion of the maximum deductible drive torque. As a result, the occurrence of traction on the motor-driven wheels is prevented or at least reduced.
- the reference speed mentioned in the introduction is preferably determined from the wheel speeds of those wheels whose drive torque is controlled.
- the invention is in all vehicles with multiple drive motors
- Slip control preferably performed on the electric drive.
- a control device which performs the drive torque control.
- Drive torque control can be from a single or from
- Fig. 1 is a schematic block diagram of a vehicle with two
- FIG. 1 shows a schematic block diagram of a vehicle 1 with an internal combustion engine 3 for driving the front axle and an electric motor 4 for driving the rear axle.
- the wheels of the front axle are designated 2a, 2b and the wheels of the rear axle 2c, 2d.
- the coefficient of friction ⁇ is estimated in a conventional manner. From this, a drive torque for the electric motor 4 can be calculated, which can be deducted maximally on the road. The electric motor 4 is now controlled so that it generates a portion of the maximum deductible drive torque. The percentage of deductible
- Drive torque can z. B. between 80% and 90% or less. As a result, the occurrence of drive slip can be prevented or reduced.
- the control of the electric motor 4 has the advantage that a control and the associated problems can be avoided.
- a vehicle reference speed which is required for the slip control on the front wheels 2a, 2b, can be determined from the rotational speeds of these wheels.
- the slip control on the front wheels and the anti-momentum control on the rear wheels are controlled by one or more control units equipped with appropriate software.
