Title: VEHICLE HAVING AN AUTOMATIC TRANSMISSION
Abstract:
The invention relates to a vehicle comprising a drive unit (1) that is drivingly connected to an automatic transmission (5), via which a drive torque is output to the vehicle wheels, comprising a control device (7) that acts on the drive unit (1) with a target torque provided via the actuation of a driving pedal (9), and comprising a transmission control device (16) that triggers at least one first gear shift-down (R6/5) in the automatic transmission (5) in the driving operation in the event of an acceleration movement, which shift-down occurs with a first driving pedal positioning (s6/5), which varies in the available driving pedal adjustment path (s) in accordance with the current driving status, wherein the driving pedal (9) is an active driving pedal that can be applied with a restoring force (F). According to the invention, in the event of an immediately upcoming triggering of the first gear shift-down (R6/5), a haptic shift-down notification (A) is generated by varying the driving pedal restoring force (F). The control device (7) has an evaluation unit (23), which evaluates whether there is a driver-side demand for the shift-down notification (A), based on current drive operating parameters. If there is no driver-side demand, the shift-down notification (A) is deactivated or suppressed.
