Drive support apparatus

A drive support apparatus, comprising:

• a sonar sensor that transmits an ultrasonic wave to an object outside of a vehicle to obtain, based on a reflected wave thereof, object information related to a distance to the object;
• a controller that permits a first drive force limitation control when the distance to the object, determined based upon the object information obtained by the sonar sensor, is longer than or equal to a predetermined distance, and permits at least one of a second drive force limitation control and an intervention brake control when the distance to the object, determined based upon the object information obtained by the sonar sensor, is shorter than the predetermined distance, wherein
• a limitation level in the second drive force limitation control is higher than that in the first drive force limitation control,
• the first drive force limitation control includes setting a predetermined upper limit for a drive force demand calculated according to an accelerator operation by a user, and
• the second drive force limitation control includes fully closing a throttle valve according to the distance to the object and a vehicle speed of a host vehicle.
