Embodiment 1

[0081] figure 1 It is a schematic diagram of main parts of a vehicle provided with the vibration damping control device according to Embodiment 1 of the present invention. In the following description, the traveling direction when the vehicle 1 normally travels is referred to as the front, and the direction opposite to the traveling direction is referred to as the rear. In addition, the sprung vibration in the following description refers to the vibration generated on the vehicle body via the suspension due to the input from the road surface to the wheels of the vehicle, for example, vibration of frequency components in the vicinity of 1 to 4 Hz, more specifically 1.5 Hz. The sprung vibration of the vehicle includes a component in the pitch direction or the jump direction (up-down direction) of the vehicle. In addition, sprung vibration damping refers to a technique for suppressing the above-mentioned sprung vibration of the vehicle.

Embodiment 2

[0123] The vibration damping control device 90 of the second embodiment has substantially the same configuration as the vibration damping control device 2 of the first embodiment, but is characterized by including the voltage of the battery 14 as the execution condition of the sprung vibration damping. The other configurations are the same as those in Embodiment 1, so descriptions thereof are omitted, and the same reference numerals are attached. Figure 5 It is a configuration diagram of main parts of the vibration damping control device of the second embodiment. Regarding the vibration damping control device 90 of the second embodiment, similar to the vibration damping control device 2 of the first embodiment, whether the engine 5 is started or stopped is used to determine whether to prohibit the sprung vibration damping control. In the vibration damping control device 90 of 2, the voltage of the battery 14 is also used in the judgment of whether to prohibit the sprung vibra...

Embodiment 3

[0139] The vibration damping control device 100 of the third embodiment has substantially the same configuration as the vibration damping control device 2 of the first embodiment, but has a disadvantage in that it determines whether to execute the sprung vibration damping based on the presence or absence of the catalyst 45 warm-up request. feature. The other configurations are the same as those in Embodiment 1, so descriptions thereof are omitted, and the same reference numerals are attached. Figure 8 It is a configuration diagram of main parts of the vibration damping control device of the third embodiment. The vibration damping control device 100 of the third embodiment uses whether or not there is a request to warm up the catalyst 45 in determining whether to prohibit the sprung vibration damping control. Therefore, in the vibration damping control device 100 of Embodiment 3, the processing unit 61 of the main ECU 50 has an accelerator opening acquisition unit 62, a drivi...

Abstract

An sprung vibration damping for suppressing sprung vibration which is generated to a vehicle 1 by an input from a road surface to wheels 20 provided with the vehicle 1 by controlling a torque of a motor 10, and the sprung vibration damping is subjected to a restriction including a prohibition in response to a state of a battery 14, which supplies power to the motor 10, such as a voltage and a temperature of the battery or a state of a control, which affects the power of the battery 14, such as a charge / discharge amount feedback control and the like. With the operation, the sprung vibration damping can be restricted in a state in which there is a possibility that it is difficult to appropriately execute the sprung vibration damping, in a state in which the battery 14 is liable to be deteriorated, and further in a state in which there is a possibility that the sprung vibration damping interferes with the other control. Accordingly, the sprung vibration damping can be executed in a state that the control is compromised as necessary, and thus the sprung vibration damping and the other control can be properly executed. As a result, it can be suppressed that the other control is under the influence of the execution of the sprung vibration damping control.

Description

technical field [0001] The invention relates to a vibration damping control device. In particular, the present invention relates to a vibration damping control device for suppressing vibration on the side of a vehicle body relative to a suspension device of a vehicle. Background technique [0002] During the running of the vehicle, sometimes due to the driving operation performed by the driver or the disturbance during the running of the vehicle, the vibration on the side of the vehicle body than the suspension of the vehicle, that is, the so-called sprung vibration, may cause the attitude of the vehicle to change. This attitude change causes the ground contact load of each wheel to change. This ground contact load affects the lateral reaction force generated at the wheels. Therefore, when the ground contact load of each wheel changes, the lateral reaction force of each wheel changes along with the change of the ground contact load. When the lateral reaction force of each ...
