Description
Technical Field
The invention relates to a method for vibration feedback for energy recuperation, a vibration feedback system for vibration feedback for energy recuperation, a computer program product, such as a computer readable program carrier, and a vehicle.
Background
For electric vehicles, kinetic energy recovery slows the speed of the vehicle, and intense kinetic energy recovery is similar to braking in effect. In normal running, the driving behavior of the electric vehicle and the fuel-powered vehicle are not so similar that the deceleration due to the recovery of kinetic energy is not the same as expected, thereby causing discomfort.
Therefore, when the driver looses the oil filling pedal to perform action recovery, the driver is reminded in a vibration feedback mode to achieve the possibility of converging reality and expectation.
Currently, a method of performing vibration feedback on a driver is known in the art, in which vibration feedback is issued corresponding to the direction and intensity of threat information of a vehicle and an operation mode of the vehicle to remind the driver to ensure driving safety.
However, the prior art is still deficient in delivering vibratory feedback with respect to kinetic energy recovery, and there is a continuing need for improvement.
Disclosure of Invention
It is an object of the invention to provide a method for vibration feedback for kinetic energy recovery, a vibration feedback system for vibration feedback for kinetic energy recovery, a computer program product, such as a computer readable program carrier, and a vehicle, such as for alerting a driver about a kinetic energy recovery status. The invention can realize the following advantages: the driver can feel the vehicle state more directly, and the uncomfortable feeling caused by the fact that the deceleration is different from the expectation due to the recovery of the kinetic energy is avoided, so that the driving comfort is improved.
According to a first aspect of the present invention, there is provided a method for regenerative shock feedback for a vehicle, the method comprising the steps of:
s1: acquiring the current driving state of the vehicle;
s2: judging whether the vehicle is in a kinetic energy recovery state or not; and
s3: and if the vehicle is in the kinetic energy recovery state, sending vibration feedback to remind a driver.
The invention comprises in particular the following technical concepts: first, the current driving state of the vehicle is acquired. Then, it is determined whether the vehicle is in a kinetic energy recovery state based on the obtained current driving state. Alternatively, the determination is made, for example, by: and detecting a driving current, and when the value of the driving current is less than 0, namely when the battery is charged through kinetic energy recovery, determining that the current driving state is a kinetic energy recovery state. And finally, if the vehicle is in the kinetic energy recovery state, sending vibration feedback to remind a driver. In particular, in the case of a driver not braking, a shock feedback is issued for kinetic energy recovery. Thereby, it is achieved in an advantageous manner: the driver can be made aware of the recovery of the kinetic energy, thereby eliminating the uncomfortable feeling caused by the deceleration due to the recovery of the kinetic energy being different from the expected one.
Optionally, the shock feedback corresponds to a change in intensity of kinetic energy recovery. Thus, the driver can clearly perceive the current strength of kinetic energy recovery through vibration feedback.
Optionally, the vibrational feedback is based at least on frequency and/or intensity variations. Thereby, different intensities of kinetic energy recovery can be represented by frequency and/or intensity variations of the vibrations. For example, the frequency and/or intensity of the vibration may increase as the intensity of the kinetic energy recovery increases.
Optionally, the method further comprises the steps of:
s4: ending the vibration feedback when the value of the driving current is greater than or equal to 0.
According to a second aspect of the present invention there is provided a vibrational feedback system for kinetic energy recovery of a vehicle for implementing the method according to the first aspect of the present invention, the vibrational feedback system comprising:
-a control unit capable of issuing control signals depending on the driving state of the vehicle; and
-a vibration unit capable of emitting a vibration feedback in dependence of the control signal.
Optionally, the vibration unit is arranged at the accelerator pedal and/or at the resting pedal. Alternatively, the vibrating unit may also be arranged at other locations that are easily perceived by the driver, such as in a vehicle seat, a steering wheel, a smart wearable device, and the like. This achieves the advantage that a vibration feedback can be provided to the driver continuously, so that the driver can always perceive the kinetic energy recovery state.
Optionally, the control signal comprises a frequency and/or intensity of the vibrational feedback. In this case, predetermined vibration frequencies and vibration intensities may be stored in the control unit for different degrees of kinetic energy recovery, so that corresponding vibration frequencies and vibration intensities are transmitted to the vibration unit via control signals in the state of kinetic energy recovery and are sent out corresponding vibration feedback. Alternatively, different vibration patterns may be set for different degrees of kinetic energy recovery, which may be fade-in and fade-out, alternating or other driver-discernable patterns of vibration frequency and intensity or vibration patterns that simulate corresponding braking conditions.
According to a third aspect of the present invention, there is provided a computer program product, such as a computer readable program carrier, having stored thereon computer program instructions, which when executed by a processor, at least assist in carrying out the method according to the first aspect of the present invention.
According to a fourth aspect of the invention, there is provided a vehicle comprising a vibration feedback system according to the second aspect of the invention or a computer program product according to the third aspect of the invention.

FIG. 1 shows a vehicle 1 including a seismic feedback system 10 according to an exemplary embodiment of the invention;
fig. 2 shows a schematic view of the accelerator pedal 30 with respect to a driving state of the vehicle, wherein the accelerator pedal 30 is in a kinetic energy recovery position;

Detailed Description
In order to make the technical problems, technical solutions and advantageous effects of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Fig. 1 shows a vehicle 1 comprising a vibration feedback system 10 according to the invention, a drive system 20, an accelerator pedal 30 and a rest pedal 40. Here, the vibration feedback system 10 is provided for giving vibration feedback with respect to the kinetic energy recovery state of the vehicle 1. The vibration feedback system 10 includes a control unit 11 and a vibration unit 12. In the present embodiment, the vibration unit 12 is disposed at the accelerator pedal 30. However, alternatively, the vibration unit 12 may be disposed at the rest pedal 40 or other location easily perceived by the driver, such as in a vehicle seat, a steering wheel, a smart wearable device, or the like.
The control unit 11 is able to acquire the current driving state of the vehicle 1 from the drive system 20 and issue a control signal S for controlling the vibration unit 12 to issue a vibration feedback based on the current driving state. Here, the control signal may include information about, for example, the frequency, intensity of the vibration or other specific vibration pattern related to the intensity of the kinetic energy recovery.
The vibration unit 12 is capable of issuing a vibration feedback based on the received control signal S. Here, the vibration feedback issued by the vibration unit 12 can vary in its frequency, intensity or vibration pattern based on the information in the control signal S. In particular, these variations are related to the intensity of kinetic energy recovery.
Fig. 2 shows a schematic representation of the accelerator pedal 30 with respect to the driving state of the vehicle, wherein the accelerator pedal 30 is in a kinetic energy recovery position. In the acceleration state of the vehicle, the vehicle motor outputs drive power, at which the value of the drive current I is greater than 0. In the kinetic energy recovery state of the vehicle, the inertia motion of the vehicle drives the vehicle motor to rotate, so that the vehicle motor can act as a generator, and the value of the driving current I is smaller than 0. Between the acceleration position (arrow at the bottom right in fig. 2) and the kinetic energy recovery position (arrow at the top left in fig. 2) of the vehicle accelerator pedal, there is a equilibrium position (shown by a dashed line in fig. 2) in which the vehicle motor neither outputs drive power nor recovers kinetic energy, i.e. the magnitude of the drive current I is 0. When the accelerator pedal 30 is positioned above this equilibrium position, as shown in fig. 2, the vehicle is subjected to kinetic energy recovery.
Fig. 3 shows a flow chart of a method for vibration feedback for kinetic energy recovery of the vehicle 1 according to an exemplary embodiment of the present invention. The method may be implemented, for example, using a seismic feedback system 10 according to fig. 1 and 2.
In step S1, the current driving state of the vehicle 1 is acquired. Here, for example, the control unit 11 acquires the front driving state from the driving system 20.
Next, in S2, it is determined whether or not the current driving state is the kinetic energy recovery state. In the present embodiment, the determination is made, for example, by: and detecting a driving current I, and judging that the current driving state is a kinetic energy recovery state when the value of the driving current I is less than 0. Here, the value of the drive current I is obtained from the drive system 20 through the control unit 11.
In step S3, if it is determined that the vehicle is in the kinetic energy recovery state, vibration feedback is given. Here, the vibration feedback is given by the vibration unit 12, so that the driver perceives that kinetic energy recovery is in progress.
Alternatively, a drive current I is detected in step S4, and the vibration feedback is ended when the value of the drive current I is greater than or equal to 0.
Although specific embodiments of the invention have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present invention.
