1. A driving evaluation device for evaluating a driver's skill in driving a vehicle, the driving evaluation device comprising:
a section detector that configured to detect a deceleration section and an acceleration section in cornering;
an evaluator that configured to evaluate driving based on a front-rear acceleration and a lateral acceleration in the deceleration section and a front-rear acceleration and a lateral acceleration in the acceleration section; and
a display configured to notify a user of results of an evaluation by the evaluator,
wherein the evaluator is configured to perform processes for
calculating an acceleration norm in the deceleration section based on the front-rear acceleration and the lateral acceleration in the deceleration section,
calculating an acceleration norm in the acceleration section based on the front-rear acceleration and the lateral acceleration in the acceleration section,
calculating an acceleration norm average value over the entire deceleration section by averaging the acceleration norm in the deceleration section,
calculating an acceleration norm average value over the entire acceleration section by averaging the acceleration norm in the acceleration section,
evaluating the driver's skill based on a coordinate of the acceleration norm average value in the deceleration section and the acceleration norm average value in the acceleration section as a horizontal axis and a vertical axis, respectively.
