The invention discloses a manufacturing method of a steering column support, the steering column support and a vehicle, and the manufacturing method comprises the following steps: designing a prototype product according to the total arrangement space of the steering column support, and dividing the prototype product into a non-topological domain and a topological domain; establishing a statics model of the steering column bracket; taking the volume ratio of the minimum value of the first-order modal frequency to the minimum volume of the topological region as a constraint variable; carrying out topological optimization modeling and analysis according to the statics model, the constraint variable of the steering column bracket and the target function; and a topological optimization result is interpreted, a formed product is obtained, and the formed product designs a crossed connecting arm assembly between the two bases on the basis of a mechanical transmission path and a liquid pressure casting process. A topological optimization result is interpreted by combining a processing technology, modal requirements and strength requirements, so that low-cost and high-performance lightweight design of the steering column bracket can be realized, and the influence on the comfort of a driver due to large vibration of a steering wheel in a vehicle moving process is avoided.
