A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

A replacement indicator for a shock absorber includes a pressure sensor which monitors pressure of operating fluid inside the shock absorber. The replacement indicator includes an indicative mechanism operatively coupled with the pressure sensor. The indicative mechanism includes an indicator component coupled to the shock absorber. The indicator component gets displaced relative to an outer surface of the shock absorber when the pressure of the operating fluid drops below a threshold pressure.

An object of the present invention is to provide a new load measuring apparatus for a construction machine that enables more enhancing measurement precision by monitoring a condition of a suspension cylinder. The load measuring apparatus for a construction machine according to the present invention is provided with a loading weight arithmetic module 111 that calculates a loading weight on the basis of loads of plural suspension cylinders 51 and a loading weight confirmation module 112 that outputs the calculated loading weight when the loads of the suspension cylinders 51 are all equal to or larger than a specified value and makes the calculated loading weight ineffective without outputting the loading weight when any one of the loads is below the specified value.
