Shift map switching control unit
First Claim
1. A shift map switching control unit, comprising:
- a plurality of load sensors including a rider load sensor that senses the seating of a rider on a vehicle, a passenger load sensor that senses the seating of a passenger on the vehicle and a cargo load sensor that senses the loading of cargo on the vehicle;
a plurality of shift maps for deriving shift timing of an automatic transmission, anda controller for selecting one shift map of said plurality of shift maps according to output signals from said plurality of load sensors, and controls the shift timing of the automatic transmission according to the selected one shift map,wherein said controller switches from the selected one shift map to another shift map when the seating of the rider is sensed by the rider load sensor and at least one of the seating of the passenger and the loading onto the carrier of the cargo is sensed by at least one of said plurality of load sensors.

Abstract
A controller selects a shift map for deriving the shift timing of an automatic transmission according to output signals from a front seat seating sensor, a pillion seating sensor and a carrier loading sensor. The controller switches the shift map of a standard type to an output-emphasizing type shift map when the seating of the rider is sensed and at least one of the seating of the passenger and the loading on the carrier is sensed. The controller judges the seating of the rider or the loading of the cargo when a load equal to or exceeding a predetermined value is continuously applied to each load sensor for predetermined time or longer. Load sensors that can measure weight are used and a shift map may be also selected based upon a total value of loaded weight.
