Embodiment Construction

[0026] In the single track model, the wheels of (each) axle are summed in the vehicle centerline. Thus one front wheel and one rear wheel can be seen, on which the force indicated by VA acts and on which the force indicated by HA acts. Yaw moment M z Acts on the center of gravity SP of the vehicle.

[0027] according to figure 1 , during forward acceleration, the force F 驱动，VA acting on the front wheel, the force F 驱动，HA acting on the rear wheel. at forward acceleration a 加速 , the vehicle tends to pitch backwards, so that the lift force shown by the circle (the force acting downward along the vertical axis of the vehicle) is greater at the rear than at the front, see F at the rear z，HA Marked circle and preceded by F z，VA marked circle. The lifting surface (product) also increases with the lifting force (the value of the force is proportional to the diameter of the circle), so in the forward acceleration a 加速 Lateral force F acting on the rear wheel y，HA Comparable t...

Abstract

According to the prior art, when a motor vehicle passes through a bend and load change occurs, yaw rate is reduced through brake on at least wheel, thereby stabilizing the motor vehicle. In the method of the invention, yaw rate is increased purposely, so as to obtain the known driving feeling of the engine with larger drag torque in the motor vehicle with small engine drag torque.

Description

technical field [0001] The invention relates to a method for operating a motor vehicle when driving through a curve. In this method, the occurrence of a load shift is checked. When the driver of the vehicle quickly withdraws the accelerator pedal, "off the accelerator", that is to say when transitioning from traction operation to coasting / thrust operation (Schubbetrieb), this is called a load shift. In the method according to the invention, when a load change occurs or due to the occurrence of a load change, additional braking is triggered at at least one wheel. Background technique [0002] Said solution is known from DE 196 07 185 A1. The aim here is to stabilize the driving of the vehicle by accurately balancing the yaw moment that occurs without the additional brake by an anti-yaw moment by the additional brake. According to DE 196 07 185 A1, therefore, the motor vehicle is driven essentially without yaw moments. [0003] It is also known from DE 10 2008 009 153 A1 t...
