Abstract
A gearshift control apparatus of a vehicle includes: a sensor configured to measure a speed, a brake position sensor (BPS) value, and an accelerator position sensor (APS) value of the vehicle, and a controller configured to, in a gearshift section spaced apart by a preset distance from a speed bump located on a road on which the vehicle travels, (i) calculate a deceleration of the vehicle and a gradient of the road after the speed bump, (ii) determine a correction factor corresponding to the deceleration of the vehicle and the gradient of the road, and (iii) perform a gearshift to a shift stage corresponding to the correction factor and the speed of the vehicle.
Claims18
A gearshift control apparatus of a vehicle, comprising:
- a sensor configured to measure a speed, a brake position sensor (BPS) value, and an accelerator position sensor (APS) value of the vehicle;
- and
- a controller configured to, in a gearshift section spaced apart by a preset distance from a speed bump located on a road on which the vehicle travels, (i) calculate a deceleration of the vehicle and a gradient of the road after the speed bump, (ii) determine a correction factor corresponding to the deceleration of the vehicle and the gradient of the road, and (iii) perform a gearshift to a shift stage corresponding to the correction factor and the speed of the vehicle.
A method for controlling a gearshift of a vehicle, the method comprising:
- measuring, by a sensor, a speed, a brake position sensor (BPS) value, and an accelerator position sensor (APS) value of the vehicle;
- calculating, by a controller, in a gearshift section spaced apart by a preset distance from a speed bump located on a road on which the vehicle travels, a deceleration of the vehicle and a gradient of the road after the speed bump;
- determining, by the controller, a correction factor corresponding to the deceleration of the vehicle and the gradient of the road;
- and
- performing, by the controller, a gearshift to a shift stage corresponding to the correction factor and the speed of the vehicle.
