Abstract
A method for correcting a battery state of charge (SOC) of a vehicle includes dividing a roadway segment of a roadway in front of the vehicle into at least two or more segments; obtaining roadway information for each segment of the at least two or more segments of the roadway, determining an expected battery SOC demand value of each segment based on the obtained roadway information, determining whether to correct the expected battery SOC demand value of the each segment based on whether the at least two or more segments have continuous gradients, and based thereon, performing correction of the expected battery SOC demand value.
Claims20
A method for correcting a battery state of charge (SOC) of a vehicle, the method comprising:
- dividing a roadway segment of a roadway in front of the vehicle into at least two or more segments;
- obtaining roadway information for each segment of the at least two or more segments of the roadway;
- determining an expected battery SOC demand value of each segment based on the obtained roadway information;
- and
- determining whether to correct the expected battery SOC demand value of each segment based on whether the at least two or more segments have continuous gradients, and based thereon, performing a correction of the expected battery SOC demand value.
A device for correcting a battery state of charge (SOC) of a vehicle by controlling a battery SOC demand value based on roadway information, the device comprising:
- a memory configured to store at least one instruction;
- a processor configured to execute the at least one instruction stored in the memory, and configured to divide a roadway segment of a roadway in front of the vehicle into at least two or more segments;
- and
- a peripheral device configured to obtain roadway information for each segment of the at least two or more segments,
- wherein the processor is further configured to:
- determine an expected battery SOC demand value based on the roadway information of each segment that is input from the peripheral device;
- and
- determine whether to correct the expected battery SOC demand value of each segment, based on whether the at least two or more segments have continuous gradients, and based thereon, perform a correction of the expected battery SOC demand value.
