Definitions
- the invention relates to a method for automatically stabilizing a flight attitude of a bicycle, a control device, a computer program product, a computer-readable medium, and a bicycle.
- Bicycles with electric (auxiliary) drives such as e-bikes and pedelecs
- auxiliary drives such as e-bikes and pedelecs
- eMTBs Sporty e-mountain bikes
- These eMTBs are also suitable for riding over various obstacles and performing jumps in the terrain, in bike parks, etc.
- controlled jumping requires advanced skills on the part of the rider.
- An incorrect jumping technique can quickly lead to a fall, as incorrect balance, incorrect weight shifting, or incorrect timing can lead to a critical flight position when jumping, which in most cases cannot be corrected.
- the level of difficulty is also increased by the higher weight of the eMTB compared to a regular mountain bike without electric (auxiliary) drive. beginnerers in particular are overwhelmed here.
- the invention is based on the object of increasing the safety of jumps with bicycles with electric (auxiliary) drives, even for inexperienced drivers.
- This object is achieved by a method for automatically stabilizing a flight attitude of a bicycle with the features according to claim 1, a control device with the features according to claim 4, a computer program product with the features according to claim 6, a computer-readable medium with the features according to claim 7, and by a bicycle with the features according to claim 8. Further developments are contained in the subclaims and result from the following description.
- a current pitch angle of the bicycle is determined when the bicycle performs a jump. The current pitch angle is compared to a pitch angle threshold interval.
- a braking intervention or a negative torque pulse is initiated on a rear wheel of the bicycle, so that the pitch angle is then within the pitch angle threshold interval, or if the pitch angle threshold interval is exceeded by the current pitch angle a positive torque pulse is introduced to the rear wheel of the bicycle so that the pitch angle is then within the pitch angle threshold interval
- the term bicycle is understood to mean all vehicles that have both an electric (auxiliary) drive and a muscle-powered drive, whereby the bicycle can be driven either purely by muscle power or purely electrically or in hybrid operation by both muscle power and electrically.
- the bicycle has a pedal crank unit and an electric drive system.
- the bicycle can also include a bicycle transmission, which can be, for example, a multi-speed transmission with a planetary design or a CVT transmission or similar.
- the bicycle transmission can then be operatively connected to the electric drive system.
- the bicycle transmission can be operatively connected to the pedal crank unit.
- the bicycle gear can be designed as a bottom bracket gear or as a hub gear.
- the bicycle can be designed, for example, as an e-bike, (S-)Pedelec, eMTB or as another suitable vehicle.
- the procedure can be activated by the rider of the bike when the bike is in motion if he or she wants assistance when jumping with the bike, or the procedure can be permanently active so that it is carried out automatically with every jump.
- the procedure can also be deactivated by the rider if he or she does not want assistance when jumping with the bike.
- a flight position is any position of the bicycle in which the wheels of the bicycle are completely in the air and the bicycle no longer has contact with the ground.
- a distinction can be made between a stable flight position and a critical flight position. A stable flight position exists when the bicycle and rider are in the air in such a way that a safe landing can be carried out, so that the bicycle can continue riding without problems after the jump has been completed.
- the driving dynamics namely yaw, pitch and roll movements
- a critical flight position exists when the bicycle and rider are in the air in such a way that a safe landing cannot be carried out, so that the bicycle tips over or rolls over after the jump has been completed, causing the rider to fall.
- a first step of the method it is determined whether the bicycle has jumped. This is preferably done using acceleration sensors, whereby the acceleration can be determined with respect to all three coordinate axes of the bicycle. Alternatively, this can be done using at least one yaw rate sensor.
- the acceleration sensors or yaw rate sensors can, for example, be installed on the bicycle or be part of an external unit, for example a mobile device such as a smartphone, smartwatch, fitness tracker or similar.
- the jump can be determined by the compression of the bicycle suspension fork. If this is not compressed but hangs freely in the air, this suggests that the bicycle is not in contact with the ground. This can be determined using sensors, for example by determining the suspension travel.
- the sensor data is transmitted to the control device that has the bicycle.
- the control device is connected to the corresponding sensors in a signal-effective manner.
- a signal-effective connection is such that data and signal exchange between the connection partners is possible.
- each connection partner has a corresponding interface.
- Data and signal transmission can be either wired or wireless.
- the control device and also the corresponding sensors therefore have interfaces that enable such a connection. If the sensor data from the external unit is to be used, data and signals are exchanged between the external unit and the control device of the bicycle, for example via a radio connection or by means of wired communication.
- a pitch angle refers to the angle that the bicycle assumes when it is moved about its transverse axis, i.e. when it performs a pitching movement in the driving dynamic sense.
- the transverse axis is a purely geometric axis that runs parallel to the crank axis.
- a pitch angle of 0° corresponds to the bike traveling on a flat, straight route.
- a positive pitch angle corresponds to a lifting of a front wheel of the bicycle.
- a negative pitch angle corresponds to a lowering of the front wheel of the bike.
- the pitch angle is determined sensorily.
- the pitch angle can be determined using an inclination angle sensor that the bicycle has.
- the pitch angle can be determined using the sensor system of the external unit, which is arranged on the bicycle.
- the current pitch angle is compared with a pitch angle threshold interval.
- the pitch angle threshold interval includes all possible pitch angles that the bike can assume during a jump so that a safe landing is then possible.
- the pitch angle threshold interval can cover the range [-25°, 25°], the range [-20°, 20°], the range [-15°, 15°], the range [-20°, 0°], the range [-25°, 0°], the range [-15°, 0°] or other suitable pitch angle ranges. It has been shown that a pitch angle of -25° or 25° represents a limit for a just about safe landing after a jump.
- threshold or “threshold interval” does not refer to a global limit value that cannot physically be exceeded or undercut. Rather, it is a specific value set by a user. All values are to be understood as including tolerances. If the current pitch angle determined is within the pitch angle threshold range, the flight position is stable. The rider can land safely with the bike after the jump. However, if the current pitch angle is outside the pitch angle threshold range, there are two alternatives for the fourth step of the procedure.
- the pitch angle exceeds the pitch angle threshold interval.
- the control device then controls the electric drive system of the bicycle so that a negative torque pulse is initiated at the rear wheel of the bicycle. The wheel thus rotates in the opposite direction to the driving direction during the jump.
- the control device controls the brake system of the bicycle so that a braking torque is initiated on the rear wheel.
- the braking system can include, for example, an ABS system. Both measures reduce the pitch angle so that it then lies within the pitch angle threshold interval. This stabilizes the flight attitude of the bike and the rider can land safely and easily after the jump.
- the pitch angle falls below the pitch angle threshold interval.
- the control device then controls the bicycle's electric drive system so that a positive torque pulse is introduced at the bicycle's rear wheel. The wheel thus rotates in the drive direction during the jump. This measure increases the pitch angle so that it then lies within the pitch angle threshold interval. This also stabilizes the bicycle's flight position and the rider can land safely and easily after the jump.
- the intensity of the positive torque pulse and/or the negative torque pulse and/or the braking intervention depends on the difference between the pitch angle threshold interval and the current pitch angle.
- a calculation model is used to calculate how strong the respective torque pulse or braking intervention must be so that the pitch angle has a predetermined value occupies, for example -15°, -10°, -20°, -25°, 0°, 15°, 10°, 20°, 25°, or similar suitable values.
- This predetermined pitch angle value can, for example, be identical for all jumps or can be calculated individually using another calculation model depending on the load on the bicycle.
- a control device for a bicycle can be connected in a signal-effective manner to an electric drive system of the bicycle, and the control device comprises means for carrying out the method that has already been described in the previous description.
- the control device can be designed, for example, as a domain ECU or as an ECU.
- control device If the control device is used in a bicycle, it is connected to the electric drive system, more precisely to the actuator system of the electric drive system, in a signal-effective manner, so that the control device can control the actuator system.
- the control device can therefore request a positive torque pulse or a negative torque pulse. Furthermore, the control device can sense what torque is currently present.
- control device is used in a bicycle, it is additionally connected to at least one sensor in a signal-effective manner.
- the control device receives data from the sensors, for example, on the acceleration, rotation rate and pitch angle and, if applicable, on the suspension travel of the suspension fork.
- the control device can be connected to an acceleration sensor or rotation rate sensor, to an inclination angle sensor and/or to a mobile device, and, if applicable, to a travel sensor for determining the suspension travel.
- the control device is connected to the mobile device, the latter can receive data and signals from the mobile device that the sensors in the mobile device record.
- the control device can use the inclination angle data, speed data, acceleration data, GPS data, or similar from the mobile device.
- the control device can also be connected to a braking system of the bicycle in a signal-effective manner. If the control device is used in a bicycle these are additionally connected to the brake system in a signal-effective manner, more precisely to the actuator system of the brake system, so that the control device can control the actuator system. The control device can therefore request a braking intervention.
- a computer program product includes commands which, when the program is executed by the control device already described, cause it to carry out the method already described.
- a computer-readable medium comprises instructions which, when executed by the control device described above, cause it to carry out the method described above.
- the computer-readable medium can be embodied, for example, as a data carrier or as a downloadable data stream.
- the bicycle has the electric drive system and the control device already described, the electric drive system being connected to the control device in a signal-effective manner.
- the control device can thus control the actuators of the electric drive system so that a positive or negative torque pulse can be requested.
- the bicycle can therefore carry out the method for automatically stabilizing a flight attitude of the bicycle, which has already been described.
- the bicycle also has the pedal crank unit.
- the electric drive system has at least one electric motor and an electrical energy storage device.
- the bicycle also has the bicycle transmission. Both the pedal crank unit and the electric drive system are connected to the bicycle transmission.
- the bicycle has several sensors that are connected to the control device in a signal-effective manner, e.g. speed sensors, acceleration sensors, rotation rate sensors, travel sensors, inclination angle sensors, and/or a mobile device.
