Drive assistance device for saddle type vehicle
A drive assistance device ( 24 ) for a saddle type vehicle ( 1 ) includes a ride sensor ( 37 ) configured to detect a ride attitude of a rider (J), a vehicle body behavior generating part ( 25 ) configured to generate a behavior on a vehicle body by a prescribed output, and a controller ( 27 ) configured to control driving of a plurality of devices (BR, EN, ST) included in the vehicle body behavior generating part ( 25 ), and, when at least one of the plurality of devices (BR, EN, ST) is actuated regardless of the operation of the rider (J), the controller ( 27 ) determines which of the plurality of devices (BR, EN, ST) is to be actuated according to the ride attitude of the rider (J) detected by the ride sensor ( 37 ).
1. A drive assistance device for a saddle type vehicle comprising:
a ride sensor configured to detect a ride attitude of a rider;
a vehicle body behavior generating part configured to generate a behavior on a vehicle body by a prescribed output; and
a controller configured to control driving of a plurality of devices included in the vehicle body behavior generating part,
wherein, when at least one of the plurality of devices is actuated regardless of an operation of the rider, the controller determines which of the plurality of devices is to be actuated according to the ride attitude of the rider detected by the ride sensor.
2. The drive assistance device for a saddle type vehicle according to claim 1 , comprising, a handle to which the rider performs a steering operation,
the ride sensor includes a grip sensor that is disposed on a grip of the handle and that is configured to detect a gripped state of the rider, and
the controller detects the ride attitude of the rider according to the gripped state of the rider detected by the grip sensor.
3. The drive assistance device for a saddle type vehicle according to claim 2 , wherein the handle comprises a pair of left and right grips,
the ride sensor comprises a pair of left and right grip sensors disposed on the pair of left and right grips, respectively, and
the controller detects a ride attitude of the rider according to a crosswise difference between the gripped states of the rider detected by the pair of left and right grip sensors WO.
4. The drive assistance device for a saddle type vehicle according to claim 2 , wherein the grip sensor detects a load direction with respect to the grip, and
the controller detects a ride attitude of the rider according to the load direction detected by the grip sensor.
5. The drive assistance device for a saddle type vehicle according to claim 2 , wherein the grip sensor detects an oscillation frequency of the grip, and
the controller detects a ride attitude of the rider according to the oscillation frequency detected by the grip sensor.
6. The drive assistance device for a saddle type vehicle according to claim 1 , comprising; a step on which the rider puts his/her foot,
the ride sensor comprises a step sensor disposed on the step and
the controller detects a ride attitude of the rider according to a footrest state of the rider detected by the step sensor.
7. The drive assistance device for a saddle type vehicle according to claim 6 , comprising; a pair of left and right steps on both sides of a vehicle body,
the ride sensor comprises a pair of left and right step sensors disposed on the pair of left and right steps respectively, and
the controller detects a ride attitude of the rider according to a crosswise difference between the footrest states of the rider detected by the pair of left and right step sensors.
