Abstract
A speed control device includes: a vehicle information output unit that outputs at least two, as vehicle information, of measurement information on forward/backward acceleration of a vehicle measured by an acceleration sensor, forward/backward actual acceleration of the vehicle obtained from an output rotation of an automatic transmission, and a traveling driving force based on a driving force output by a driving source and an air resistance acting on the vehicle; and a setting unit that selects a shift mode by comparing the vehicle information with a predetermined selection threshold and sets a shift point for controlling the automatic transmission provided in the vehicle based on the shift mode.
Claims8
A speed control device comprising:
- a vehicle information output unit that outputs at least two, as vehicle information, of measurement information on forward/backward acceleration of a vehicle measured by an acceleration sensor, forward/backward actual acceleration of the vehicle obtained from an output rotation of an automatic transmission, and a traveling driving force based on a driving force output by a driving source and an air resistance acting on the vehicle;
- and
- a setting unit that selects a shift mode by comparing the vehicle information with a predetermined selection threshold and sets a shift point for controlling the automatic transmission provided in the vehicle based on the shift mode.
A speed control device, comprising:
- a vehicle information output unit that outputs, as vehicle information, measurement information on forward/backward acceleration of a vehicle measured by an acceleration sensor, forward/backward actual acceleration of the vehicle obtained from an output rotation of an automatic transmission, and a traveling driving force based on a driving force output by a driving source and an air resistance acting on the vehicle;
- and
- a setting unit that calculates traveling resistance from the vehicle information and sets a shift point for controlling the automatic transmission provided in the vehicle based on the traveling resistance.
A speed control device, comprising:
- a vehicle information output unit that outputs the acceleration sensor value based on the forward/backward acceleration of the vehicle measured by the acceleration sensor, and the traveling driving force based on the driving force of the driving source of the vehicle and the air resistance acting on the vehicle,
- a setting unit that calculated the correction value by which correct the acceleration sensor value based on a plurality of the acceleration sensor values and a plurality of the traveling driving forces, and corrected the acceleration sensor value based on the correction value, and the acceleration is calculated.
