Abstract

The mobile body includes: a stepped transmission; a clutch; a control device; a drive source; an output detection means that acquires an output of the drive source; and an acceleration detection means that acquires acceleration; in which the control device includes: a travel resistance calculation means that calculates a travel resistance based on the acceleration; and a clutch capacity setting means that performs clutch capacity setting based on the output and the travel resistance.

First claim

What is claimed is:

1. A mobile body comprising:
a stepped transmission;
a clutch;
a control device including a processor;
a drive source that is an engine or a motor;
an output detection sensor that acquires an output of the drive source; and
an acceleration detection sensor that acquires acceleration;
wherein the processor of the control device includes:
a travel resistance calculation means that calculates a travel resistance based on the acceleration;
a clutch capacity setting means that performs clutch capacity setting based on the output and the travel resistance;
a shift state determination means that determines whether or not the stepped transmission is performing a shifting operation; and
a comparison means that compares the output with the travel resistance when it is determined that the stepped transmission is not shifting,

wherein the clutch capacity setting means sets a clutch capacity based on a value of either of the output or the travel resistance determined to be larger by the comparison means.

2. The mobile body according to claim 1 , further comprising
a road surface gradient angle detection sensor that detects a road surface gradient angle,
wherein the travel resistance calculation means calculates the travel resistance based on the road surface gradient angle.

3. The mobile body according to claim 1 , further comprising
a turning angle detection means that detects a turning angle of the mobile body,
wherein the travel resistance calculation means calculates the travel resistance based on the turning angle.

4. A mobile body control method comprising:
an output acquisition step of acquiring an output of a drive source;
an acceleration acquisition step of acquiring acceleration;
a travel resistance calculation step of calculating a travel resistance based on the acceleration;
a clutch capacity setting step of setting a clutch capacity based on the output and the travel resistance;
a shift state determination step of determining whether or not a stepped transmission is performing a shifting operation; and
a comparison step of comparing the output with the travel resistance when it is determined that the stepped transmission is not shifting,
wherein the clutch capacity setting step sets the clutch capacity based on a value of either of the output or the travel resistance determined to be larger in the comparison step.

5. The mobile body control method according to claim 4 , further comprising
a road surface gradient angle detection step of detecting a road surface gradient angle,
wherein the travel resistance calculation step calculates the travel resistance based on the road surface gradient angle.

6. The mobile body control method according to claim 4 , further comprising
a turning angle detection step of detecting a turning angle of the mobile body,
wherein the travel resistance calculation step calculates the travel resistance based on the turning angle.
