Problems solved by technology

While the dynamics of a vehicle in response to driver input can be simulated or measured, this understanding does not define the question of 'good handling' unless complemented by a human being as to how the control system works and how the driver's brain is involved in vehicle control working understanding

Embodiment Construction

[0049] figure 1 The dynamics of a motor vehicle are disclosed in six degrees of freedom, shown as follows:

[0050] Up and down motion = heave

[0051] side to side movement = swing (sway)

[0052] Fore and aft motion = bump (surge)

[0053] Angle change around the horizontal direction Y = pitch;

[0054] Angle change around vertical Z = yaw; and

[0055] Angle change around the horizontal longitudinal direction x = roll.

[0056] figure 2 A motor vehicle comprising a vehicle body 1 and an engine-transmission system comprising an engine 2 and a transmission 3 is disclosed. The engine 2 is arranged at the front of the motor vehicle. The transmission 3 includes a drive shaft 4 . The motor vehicle has two wheel suspensions, a front wheel suspension for the front wheels 5 and a rear wheel suspension for the rear wheels 6 . The drive shaft 4 connects the transmission 3 to the wheels 5, 6 in different drive configurations such as front-wheel drive, rear-wheel drive or all-...

Abstract

A motor vehicle has a wheel suspension for the rear wheel. The wheel suspension comprises wheel spindle housing (11) and a frame structure (9). Several control links extend between the frame structure (9) and the wheel spindle housing (11), and comprise a lower rear link (13), trailing and toe links (16, 17), and first and second camber links (18, 19), which intersect each other. The trailing link (16) and the lower rear link (13) form a lower triangular link swingable about a lower swing axis. The first camber link (18) and the second camber link (19) together form an upper triangular link swingable about an upper swing axis. The lower and upper swing axes form a first angle to each other in a horizontal plane lying in the interval 0-5 DEG. The lower and upper swing axes form a second angle to each other in a vertical, longitudinal plane lying in the interval 1-8 DEG.

Description

technical field [0001] The present invention relates generally to the suspension of the rear wheels of motor vehicles, especially passenger cars, sport utility vehicles (SUVs) and light trucks. More specifically, the invention relates to a wheel suspension as defined in the preamble of claim 1 . The invention also relates to a motor vehicle with such a wheel suspension. Such a wheel suspension is disclosed in WO2008 / 053034. Background technique [0002] The wheel suspension of a motor vehicle connects the structure of the sprung (sprung) vehicle mass to the structure of the unsprung and rotating tire-wheel combination. In addition, the wheel suspension controls the tire-wheel combination relative to external influences from the road and internal influences from propulsion, braking and steering initiated by the driver through the engine-transmission system, braking system, steering system and wheel suspension sport mode. [0003] The overall controllability of the vehicle...
