no. 1 approach

[0048] Hereinafter, a first embodiment of a realized steering device for a vehicle will be described with reference to the drawings.

[0049] Such as figure 1 As shown, the direction manipulator 1 of this embodiment includes: a rim 2 having a ring-shaped outer shape and held by a vehicle occupant (driver); a hub 3 connected to a steering shaft not shown; There are three spokes 4 connected between the hub 3 and the rim 2 in the shape of a lettering. In addition, the steering controller 1 of the present embodiment is provided with a capacitance sensor 11 and a heater 12, and the capacitance sensor 11 functions as a sensor element (sensor element) 10 for detecting the grip state of the driver. , the heater 12 is used to heat the rim 2 which becomes the holding part thereof.

[0050]Specifically, in the directional manipulator 1 of this embodiment, the sensor electrode 11 a of the capacitance sensor 11 and the heater wire 12 a of the heater 12 are respectively provided inside th...

[0060] Hereinafter, a second embodiment of a realized steering device for a vehicle will be described with reference to the drawings. In addition, for convenience of explanation, the same reference numerals are assigned to the same configurations as those of the above-mentioned first embodiment, and description thereof will be omitted.

[0061] Such as Figure 5 As shown, the control device 30B of this embodiment is the same as the control device 30 in the above-mentioned first embodiment (refer to figure 2 ) is the same, and includes a sensor drive unit 21B and a heater drive unit 22B. In addition, in the steering device 20B of the present embodiment, the vehicle speed V is input to the control device 30B. Furthermore, the control device 30B of the present embodiment includes a running state determination unit 33 that determines the running state of the vehicle based on the vehicle speed V.

[0062] Specifically, when the vehicle speed V exceeds the predetermined speed V0...

Abstract

The invention relates to a steering device, which can detect the holding state of a driver while heating a steering device more properly. The steering device is provided with a control device that isprovided with: a sensor drive unit that drives an electrostatic capacitance sensor, which is a sensor element provided to a steering device, so as to detect the grip state of the steering device; anda heater drive unit that drives a heater provided to the steering device. The sensor drive unit periodically performs driving of the sensor element with an interval therebetween, and the heater driveunit alternately performs heater driving with the sensor driving performed by the sensor drive unit. The steering device is configured so that the interval (t0->t1, t1 > t0) between sensor drives performed by the sensor drive unit is increased in a state in which the steering device is gripped compared to a state in which the steering device is not gripped.

Description

technical field [0001] The invention relates to a direction manipulation device. Background technique [0002] In the past, there is a device that is provided with a sensor element and a heating element (heater wire) on a steering manipulator of a vehicle. The sensor element is used to detect the driver's grip state, and the heating element holding part) for heating. For example, Patent Document 1 discloses a circuit structure that reduces intermittent operation of a heater caused by operation of a thermostat to grip detection using a sensor element (electrostatic capacitance sensor) provided to the direction manipulator. the impact. In addition, for example, Patent Document 2 discloses a configuration in which the driving of the sensor element and the driving of the heater are alternately performed (or alternatively switched). In addition, thereby, it is possible to detect the grip state of the driver with high precision while heating the steering controller. [0003] p...
