Abstract

An electric vehicle driving support system includes an acquisition unit that acquires predictive information of traffic congestion calculated based on acceleration of an electric vehicle and an economical driving mode output unit that outputs a control instruction to prioritize speed maintenance or acceleration when the predictive information of traffic congestion acquired by the acquisition unit indicates a non-congestion tendency, and that outputs a control instruction to prioritize deceleration when the predictive information of traffic congestion indicates a congestion tendency.

Claims

1. An electric vehicle driving support system comprising:

an acquisition unit that acquires predictive information of traffic congestion calculated based on acceleration of an electric vehicle; and

an economical driving mode output unit that outputs a control instruction to prioritize speed maintenance or acceleration when the predictive information of traffic congestion acquired by the acquisition unit indicates a non-congestion tendency, and that outputs a control instruction to prioritize deceleration when the predictive information of traffic congestion indicates a congestion tendency.

2. The electric vehicle driving support system according to claim 1, further comprising:

a display unit that changes a display mode depending on details of the control instruction output from the economical driving mode output unit.

3. The electric vehicle driving support system according to claim 1, further comprising:

a control unit that controls the driving of the electric vehicle depending on details of the control instruction output from the economical driving mode output unit.

4. The electric vehicle driving support system according to claim 1, further comprising:

a regeneration prioritization mode output unit that outputs a control instruction to prioritize deceleration regardless of whether the predictive information of traffic congestion indicates a non-congestion tendency or the predictive information of traffic congestion indicates a congestion tendency; and

a setting unit that sets which of the economical driving mode output unit and the regeneration prioritization mode output unit to select depending on an input from a driver.

5. The electric vehicle driving support system according to claim 2, further comprising:

a control unit that controls the driving of the electric vehicle depending on details of the control instruction output from the economical driving mode output unit.

6. The electric vehicle driving support system according to claim 2, further comprising:

a regeneration prioritization mode output unit that outputs a control instruction to prioritize deceleration regardless of whether the predictive information of traffic congestion indicates a non-congestion tendency or the predictive information of traffic congestion indicates a congestion tendency; and

a setting unit that sets which of the economical driving mode output unit and the regeneration prioritization mode output unit to select depending on an input from a driver.
