Abstract
The present invention relates to a method for controlling a suspension system of a motor vehicle comprising a vehicle body and a plurality of wheel pairs (2a/2b, 2c/2d), wherein the suspension system comprises spring members arranged for resilient connection between the wheels of the vehicle and said vehicle body. The method comprises the step of: monitoring at least one first parameter indicating braking of thee motor vehicle, and when said parameter indicates braking of the motor vehicle, preventing compression of the spring members of at least one wheel pair (2a/2b, 2c/2d) of the motor vehicle for counteracting a rotation of the vehicle body in connection to braking.
Claims19
A method for controlling a suspension system of a motor vehicle comprising a vehicle body and a plurality of wheel pairs, wherein the suspension system comprises spring members arranged for resilient connection between the wheels of the vehicle and said vehicle body, wherein the method comprises the step of:
- monitoring at least one first parameter indicating braking of the motor vehicle;
- and
- when said parameter indicates braking of the motor vehicle, preventing compression of the spring members of at least one wheel pair of the motor vehicle for counteracting a rotation of the vehicle body in connection to braking, wherein the step of preventing compression of the spring members is performed such that wheel suspension compression is prevented only if wheel forces from a ground acting on wheels in the wheel pair do not exceed a certain threshold value.
A suspension system for a motor vehicle comprising a vehicle body and a plurality of wheel pairs, wherein the suspension system comprises:
- spring members arranged for resilient connection between the wheels of the vehicle and said vehicle body;
- suspension regulating members, and
- a control unit configured to control said suspension regulating members and monitor at least one first parameter indicating braking of the vehicle,
- wherein said control unit is configured to, when said parameter indicates braking of the motor vehicle, control the suspension regulating member such that compression of the spring members of the at least one wheel pair of the motor vehicle is prevented for counteracting rotation of the vehicle body in connection to the braking, wherein the suspension regulating member and/or the control unit are configured such that compression of the spring members is prevented only if wheel forces from a ground acting on wheels in the wheel pair do not exceed a certain threshold value.
