Electronically controlled suspension system, method for controlling a suspension system and computer program
An electronically controlled suspension system for a bicycle includes at least one spring element between first and second parts the bicycle, both parts being movably interconnected. At least one parameter of the spring element is modified. At least one actuator influences the spring element to modify the at least one parameter. An electronic module produces a control signal for the at least one actuator. A control device is influenced by the control signal produced by the electronic module. The control device is connected to at least one of the electronic module and the actuator through a radio signal. A corresponding method controls the suspension system for the bicycle and a computer program executes the method.
1. A seat post for a bicycle, comprising:
an electronic module
generating a radio signal dependent upon one or more of terrain topography, velocity, acceleration, position, torque, and road surface condition; and
implements at least one first operating condition and at least one second operating condition, wherein, in the second operating condition, the number of functions that can be executed is reduced and the energy consumption is lowered as compared to the first operating condition; and
a post body having:
a first end shaped to be connected to a bicycle frame;
a second end shaped to be connected to a saddle;
at least two longitudinal portions meshing with each other and slidable relative to one another along a longitudinal extension; and
a fixing apparatus by which the two longitudinal portions can be fixed to one another in a settable relative position, the fixing apparatus being influenced to selectively fix and unfix by the radio signal.
2. The seat post according to claim 1 , wherein the two longitudinal portions are connected to each other through a gas pressure spring.
3. The seat post according to claim 1 , further comprising an antenna associated with the fixing apparatus and receiving the radio signal.
4. The seat post according to claim 1 , wherein the electronic module comprises a cell phone.
5. The seat post according to claim 1 , wherein the electronic module comprises at least one micromechanical acceleration sensor.
6. The seat post according to claim 5 , wherein the at least one micromechanical acceleration sensor is at least one multi-axis micromechanical acceleration sensor measuring acceleration in three dimensions.
7. The seat post according to claim 5 , wherein:
the at least one micromechanical acceleration sensor generates raw data; and
the electronic module determines at least one of a velocity and a position by integration of the raw data of the at least one micromechanical acceleration sensor.
8. The seat post according to claim 1 , wherein the electronic module changes from the first operating condition to the second operating condition when no acceleration is detected over a settable time period.
9. The seat post according to claim 1 , wherein the electronic module changes from the second operating condition to the first operating condition when an acceleration is detected.
10. The seat post according to claim 1 , wherein:
in the at least one first operating condition, a given number of functions can be executed and a given amount of energy is consumed; and
in the at least one second operating condition, less than the given number of functions can be executed and less than the given amount of energy is consumed.
11. The seat post according to claim 10 , wherein the electronic module automatically changes from the first operating condition to the second operating condition when the electronic module determines that no acceleration has been detected over a user-settable period of time.
12. The seat post according to claim 10 , wherein the electronic module changes from the second operating condition to the first operating condition when acceleration is detected.
13. The seat post according to claim 1 , further comprising an electronic module programmed to control at least one suspension system of the bicycle.
14. The seat post according to claim 1 , further comprising an electronic module containing a map memory storing topographic information.
15. The seat post according to claim 1 , wherein the electronic module comprises a map memory storing topographic terrain information.
