A mechanical bypass for a shock assembly is disclosed herein. The assembly has a damper chamber having a compression portion and a rebound portion. There is further an external reservoir in fluid communication with the rebound portion of the damper chamber via a flow path. A valve is coupled with the flow path, the valve to meter a flow of the working fluid through the flow path. A bypass port to the external reservoir is provided in the flow path and bypasses the valve. A mechanical relief valve is provided in the bypass port to block a fluid flow though the bypass port until a blow-off pressure that is higher than a normal operating pressure and less than a burst pressure of the damping chamber is provided thereon.

A system for a vehicle includes a memory storing a stored driver distribution profile of a driver input parameter and a stored suspension setting corresponding to the stored driver distribution profile. The system further includes a sensor to detect a current value of the driver input parameter. The system further includes a processor communicably coupled to the memory and the sensor. The processor is configured to determine a current driver distribution profile of the driver input parameter based on the current value of the driver input parameter. The processor is configured to determine a current suspension setting based on the current driver distribution profile. The processor is configured to adjust the stored suspension setting to generate a stored adjusted suspension setting corresponding to the current suspension setting.

A vehicle includes a sprung mass including a cabin coupled to a chassis, tractive assemblies each including at least one tractive element, springs coupling the tractive elements to the sprung mass, each spring imparting an upward force on the sprung mass, load sensors each configured to provide a signal indicative of the force imparted by one of the springs, and a controller operatively coupled to the load sensors. The controller is configured to determine a weight of the sprung mass using the signals from the load sensors and monitor at least one operational condition of the vehicle. The controller is configured to determine whether or not to disable determination of the weight based on the at least one operational condition.

A vehicle control device includes: a control portion that makes, of a plurality of shock absorbers included in a vehicle, a first damping force of at least one shock absorber that is located on a first direction side on which acceleration acts in a longitudinal direction of the vehicle larger than a second damping force of at least one shock absorber of the plurality of shock absorbers that is located on a second direction side opposite to the first direction in the longitudinal direction of the vehicle before acceleration acting on the vehicle is detected by an acceleration sensor due to acceleration or deceleration of the vehicle.

This invention pertains to shock absorbers, and a method of controlling their operation. Specifically, this invention relates to use of a user interface allowing to control the sensitivity of various parameters used by a programmed electronic control unit. When in operation, said electronic control unit automatically send calculated and user-adjusted electronic signals to electronic control devices which proportionally regulate flow of fluid within each shock absorbers of a vehicle.

Example illustrations are directed to a damping system for a vehicle suspension that includes a controller configured to determine a roughness of a ground surface associated with the vehicle. The controller is also configured to determine a damper setting for the damping system based on the determined roughness. A method is also provided that includes determining, using a controller, a roughness of a ground surface associated with the vehicle. The method may further include determining, using the controller, a damper setting of the vehicle based on the determined roughness.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile and a driver actuatable input. The driver actuatable input may be positioned to be actuatable by the driver in the absence of requiring a removal of either of the hands of the driver from a steering device of the vehicle.

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 vehicle includes a first actuator, one or more second actuators, and an electronic control unit. The first actuator is configured to control a stroke of a suspension for a control target wheel. The one or more second actuators is configured to control the stroke of the suspension and more responsive than the first actuator. The electronic control unit is configured to: execute a calculation process to calculate a required control amount for at least one of roll control and pitch control of the vehicle; and execute a command process to distribute and command the required control amount to the first actuator and the one or more second actuators.
