Vehicle suspension tuning system and method
Disclosed is an automatic vehicle suspension tuning system. The system has a control module to receive user input, an ECU with a processor and a memory, one or more road condition sensors, and one or more controllable suspension system components. The ECU controls the adjustments of the controllable suspension system component in response to user input to the control module as well as input from the road condition sensors during operation of the vehicle. A method of tuning a controllable suspension system component is also disclosed.
1. A vehicle suspension tuning system comprising:
an ECU coupled to a vehicle;
at least one controllable suspension system component coupled to the vehicle and coupled to the ECU, wherein the ECU is programmed to send at least one tuning signal to the at least one controllable suspension system component for tuning the at least one controllable suspension system component to a tuned setting, wherein the at least one controllable suspension system component is automatically adjusted in response to the at least one tuning signal, and wherein the at least one controllable suspension system component is a controllable shock, wherein a spring stiffness of the controllable shock is tuned in response to the at least one tuning signal, and/or a controllable sway bar, wherein a sway bar stiffness of the controllable sway bar is tuned in response to the at least one tuning signal; and
at least one road condition sensor coupled to the ECU, wherein the ECU is further programmed to make near real time tuning adjustments to the at least one controllable suspension system component in response to signals received from the at least one road condition sensor, wherein the ECU tunes the at least one controllable suspension system component to the tuned setting, in response to signals received from the at least one road condition sensor, during operation of the vehicle, and wherein the tuned setting comprises a damping rate setting, a damping rate setting range, a spring stiffness setting, a spring stiffness setting range, a sway bar stiffness setting, a sway bar stiffness setting range and/or a combination thereof.
2. The vehicle suspension tuning system of claim 1 , wherein a damping rate of the controllable shock is tuned in response to the at least one tuning signal.
3. The vehicle suspension tuning system of claim 1 , wherein the at least one road condition sensor is selected from the group consisting of a shock compression sensor, a sway bar stiffness sensor, a vehicle speed sensor, a vehicle braking sensor, a vehicle acceleration sensor, a wheel traction slippage sensor, a steering angle sensor, and any combination thereof.
4. The vehicle suspension tuning system of claim 1 , wherein the at least one tuning signal are multiple tuning signals.
5. The vehicle suspension tuning system of claim 4 , wherein the multiple tuning signals are sent in rapid succession multiple times per minute.
