A control system (100, 200) for a vehicle suspension system of a vehicle (700). The vehicle suspension system comprises an actuator coupled an anti-roll bar. The control system is configured to: receive a vehicle stationary signal (304, 404) indicative of the vehicle being stationary; output a passive state request signal to the actuator of the vehicle suspension system (306) in dependence on receipt of the vehicle stationary signal, wherein the passive state request signal is configured to prevent the actuator from responding to a received torque demand; receive a passive state confirmation signal (308) indicative that the actuator is in a passive state; output a torque demand to the actuator (310) in dependence on the passive state confirmation signal; receive a sensor response signal (312) from a sensor configured to sense a torque level of the anti-roll bar; and output a fault signal (316) in dependence on receipt of the sensor response signal indicating the torque level of the anti-roll bar is above a predetermined threshold.

A status tracking system for tracking a suspension system or a physical condition of the parts in a steering system in vehicles. The status tracking system includes a sensor unit connected with the body of the part, and a processor unit configured to connect with the sensor unit in a manner receiving the measurements made by the sensor unit as input. The processor unit is configured to obtain measurement information from the measurements it receives, generate status information by classifying the measurement information according to a reference value in a memory unit, and display the status information on a user interface.

Methods and apparatus to identify ride height sensor discrepancies are disclosed. An example apparatus disclosed herein includes machine readable instructions and programmable circuitry to at least one of instantiate or execute the machine readable instructions to compare a first sensor output of a first ride height sensor of a vehicle to a second sensor output of a second ride height sensor of the vehicle, increment a discrepancy counter based on the comparison of the first sensor output and the second sensor output, and generate an indication to service at least one of the first ride height sensor or the second ride height sensor after the discrepancy counter satisfies a threshold.

A computer system comprising processing circuitry configured to: determine a present temperature of a suspension system of a vehicle, predict a future temperature of the suspension system based on the present temperature of the suspension system, historical driving data for an upcoming road stretch for the vehicle and a suspension temperature prediction model, and provide an output that depends on the predicted temperature of the suspension system.

A method for monitoring a vehicle (1) having a vehicle superstructure (2), a chassis (3) connected to the vehicle superstructure (2), and a monitoring unit (11) which monitors the chassis (3) for damage. In the event that chassis damage is detected, the monitoring unit produces a warning signal (S) by means of a warning signal generator, where the warning signal generator has at least one drive unit (10) by means of which the warning signal (S) is produced in the form of a tactile mechanical vibration.
