Vehicle activation systems and methods for electric vehicles
Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.
1. A method of activating an electric vehicle, the method comprising:
when the electric vehicle is in an inactive state, receiving a first command to activate the electric vehicle;
in response to the first command, transitioning the electric vehicle from the inactive state to a wake state where:
a controller of the electric vehicle is activated;
the electric vehicle is prevented from being propelled by an electric motor configured to propel the electric vehicle; and
regenerative braking of the electric motor is caused when the electric vehicle is in motion causing back-driving of the electric motor;
after receiving the first command, receiving a second command to activate the electric vehicle; and
in response to the second command, transitioning the electric vehicle from the wake state to a ready state where the electric vehicle is permitted to be propelled by the electric motor.
2. The method as defined in claim 1 , comprising, in response to the first command, providing a first visual indication of a first color indicating the wake state of the electric vehicle.
3. The method as defined in claim 2 , comprising, in response to the second command, providing a second visual indication of a second color indicating the ready state of the electric vehicle.
4. The method as defined in claim 3 , wherein the first and second visual indications include an illumination of an instrument panel of the electric vehicle.
5. The method as defined in claim 3 , comprising changing the second color of the second visual indication when transitioning the electric vehicle from a forward mode of operation to a reverse mode of operation.
6. The method as defined in claim 1 , wherein transitioning the electric vehicle from the wake state to the ready state is conditioned upon an operator's authorization to operate the electric vehicle having been received.
7. The method as defined in claim 1 , comprising:
after receiving the second command, receiving a third command; and
in response to the third command, transitioning the electric vehicle from the ready state to the wake state.
8. A vehicle activation system for an electric vehicle, the vehicle activation system comprising:
an operator interface for receiving a first command and a second command to activate the electric vehicle;
one or more data processors operatively connected to the operator interface; and
non-transitory machine-readable memory storing instructions executable by the one or more data processors and configured to cause the one or more data processors to:
in response to receiving the first command to activate the electric vehicle when the electric vehicle is in an inactive state:
cause the electric vehicle to be prevented from being propelled by an electric motor configured to propel the electric vehicle; and
cause regenerative braking of the electric motor when the electric vehicle is in motion causing back-driving of the electric motor; and
in response to receiving the second command to activate the electric vehicle after receiving the first command, cause the electric vehicle to be permitted to be propelled by the electric motor.
9. The vehicle activation system as defined in claim 8 , wherein the instructions are configured to cause the one or more data processors to, in response to the first command, cause a first visual indication of a first color to be provided.
10. The vehicle activation system as defined in claim 9 , wherein the instructions are configured to cause the one or more data processors to, in response to the second command, cause a second visual indication of a second color different from the first color to be provided.
11. The vehicle activation system as defined in claim 10 , wherein the first and second visual indications include an illumination of an instrument panel of the electric vehicle.
12. The vehicle activation system as defined in claim 10 , wherein the instructions are configured to cause the one or more data processors to cause the second color of the second visual indication to be changed when the electric vehicle is transitioned from a forward mode of operation to a reverse mode of operation.
13. The vehicle activation system as defined in claim 8 , wherein the second command is configured to cause the electric vehicle to be permitted to be propelled by the electric motor conditioned upon an operator's authorization to operate the electric vehicle being received.
14. The vehicle activation system as defined in claim 8 , wherein the instructions are configured to cause the one or more data processors to, in response to receiving a third command via the operator interface after receiving the second command, cause the electric vehicle to be prevented from being propelled by the electric motor.
15. An electric powersport vehicle comprising:
an electric motor configured to propel the electric powersport vehicle;
an operator interface for receiving a first command and a second command to activate the electric powersport vehicle; and
a controller operatively connected to the operator interface, the controller being configured to:
in response to the first command to activate the electric powersport vehicle being received via the operator interface:
cause the electric powersport vehicle to be prevented from being propelled by the electric motor; and
cause regenerative braking of the electric motor when the electric powersport vehicle is in motion causing back-driving of the electric motor; and
in response to the second command to activate the electric powersport vehicle being received via the operator interface after receiving the first command, cause the electric powersport vehicle to be permitted to be propelled by the electric motor.
16. The electric powersport vehicle as defined in claim 15 , comprising a shutoff switch configurable between a vehicle-on configuration and a vehicle-off configuration, wherein the controller is configured to, in response to the second command to activate the electric powersport vehicle being received via the operator interface after receiving the first command and when the shutoff switch is in the vehicle-on configuration, cause the electric powersport vehicle to be permitted to be propelled by the electric motor.
17. The electric powersport vehicle as defined in claim 15 , wherein the operator interface includes a push button via which the first and second commands are received.
18. The electric powersport vehicle as defined in claim 15 , comprising a battery and a power electronics module, wherein the controller is configured to, in response to the first command, cause the battery to be electrically connected to the power electronics module configured to control a delivery of electric power from the battery to the electric motor.
19. The electric powersport vehicle as defined in claim 18 , wherein the controller is configured to, in response to the first command, cause charging of a capacitor of the power electronics module.
20. The electric powersport vehicle as defined in claim 15 , wherein the electric powersport vehicle is a snowmobile.
