The present invention provides methods and systems for determining the weight of a vehicle. Exemplary methods include the steps of: determining with one or more on-board sensors, a sensor output voltage; providing the sensor output voltage information to a processing unit to determine the weight of the vehicle; and displaying the weight of the vehicle on a visual display unit

Provided is an electric suspension device including an electromagnetic actuator that is provided between a body and wheel of a vehicle and generates a load for damping vibration of the body. It includes: a camera that detects preview image information of a road surface in front of the vehicle; a 3D gyro sensor that detects a sprung speed of the vehicle; a target load computation unit that computes a target load based on the preview image information and the sprung speed; and a load control unit that controls the load of the actuator by using the computed target load. When a detection result based on the preview image information indicates that the front road surface is even but a detection result based on the sprung speed indicates that the front road surface is uneven, the target load computation unit computes the target load based on the sprung speed.

An electrically powered suspension system includes: an electromagnetic actuator that is provided between a vehicle body and a wheel of a vehicle and generates a load for damping vibration of the vehicle body; an information acquisition part that acquires information on a state of a road surface ahead of the vehicle; a target load calculation part that calculates a target load for preview control based on the road surface state, and a load control part that performs load control on the electromagnetic actuator. The target load calculation part estimates an actual input timing based on the vehicle speed and calculates an adjustment start timing related to suspension characteristics, based on the estimated actual input timing. When estimating the actual input timing based on the vehicle speed, the target load calculation part applies, to the vehicle speed, a correction coefficient for correcting a fluctuation of the vehicle speed.

A method for determining road loads includes preparing a road map (15) that contains information about the local configuration of a plurality of roads. For each of a plurality of vehicles (1) a vehicle location is determined and at least one vehicle location signal (So) that characterizes the location of the vehicle concerned is generated.

For each vehicle (1) a vehicle load mass is determined and at least one vehicle load mass signal (Sm) that characterizes the vehicle load mass is generated. At least one road loading signal (Sb) that characterizes a road load is generated for each road using the vehicle load mass signals (Sm) of the vehicles (1) assigned to it.
